Domain Buying Guides

When you buy a domain name, you purchase a piece of digital real estate. But what, exactly, are you getting for your money? NameExperts.com Director Joe Uddeme unravels the elements of a domain name – so you’ll have a clearer understanding of the architecture behind them.

 

A domain name is an address you type into your web browser whenever you want to visit a website. It is arguably one of the most important assets any business can own.

While ‘domain name’ is an all-encompassing term, a domain is actually made up of multiple parts. Understanding these elements can give you a clearer picture of the domain name investing world and ensure you’re well-informed before buying a domain name or asking a skilled domain broker to negotiate the purchase of one on your behalf.

What are domains?

A domain name is a human-readable address that directs you to a particular website available on the internet. It’s akin to the address for your official residence or workplace. When someone wants to visit you, they come to your address. Similarly, when someone wants to visit a website, they type in the domain address in their web browser.

Any domain name has four main components;

  1. Domain name: The name of the domain itself.
  2. Top-Level domain (TLD): The suffix that appears after the domain name, e.g., .COM and .NET.
  3. Subdomain: A domain that is part of another primary domain. It is also known as a third-level domain.
  4. Protocol: The system that specifies how information from the domain is transferred to your web browser. It is either HTTP (insecure) or HTTPS (secure).

Take https://www.nameexperts.com/, for example.

  • NameExperts is the domain name
  • .COM is the top-level domain
  • WWW is the subdomain
  • HTTPS is the protocol

The 3 Types of Domain Names

There are three main types of domains, including:

1. Top-Level Domains

A top-level domain (TLD) is the final section of a domain name. It is the last segment of text appearing after the dot symbol. For example, in Google.com, .COM is the top-level domain.

Ever since the world wide web’s inception, .COM has been the most common top-level domain. It was originally used to designate commercial businesses but has become the de-facto TLD for most websites.

Another popular TLD is .NET. It was initially meant for internet service providers and networks but is now available to anyone who wants it. Because NET signifies network and technology, this is an ideal option for technology companies.

Yet another well-known TLD is .ORG, which was originally used to designate not-for-profit organizations. Till today, most people associate this TLD with non-profit organizations and social causes rather than commercial businesses. The .ai TLD is another popular one today – especially for tech firms.

There are two main types of top-level domains;

Generic TLD

A generic top-level domain refers to domain name endings with three or more characters, the type that you’d most likely recognize. .COM, .NET, .ORG, .INFO, and other common domain endings fall under this category.

Before 2011, there were barely two dozen domain extensions classified as generic. That year, the Internet Corporation for Assigned Names and Numbers (ICANN) expanded the number of generic domain extensions from 22 to over 1,200, opening up more opportunities for individuals and businesses to acquire domain names.

Country-Code TLD

As the name implies, these are domain extensions associated with specific countries. ICANN assigns country domain endings to each formally recognized nation and sovereign state, and these nations collect a royalty on every sale of their assigned TLD. For example, Tuvalu, a small island nation, earns 1/12th of its annual income from its .TV domain extension.

Other popular examples of country domain endings include

  • .US for the United States of America
  • .AU for Australia
  • .DE for Germany
  • .CA for Canada
  • .CC for Cocos Islands
  • .AE for the United Arab Emirates (UAE), etc.

2. Second-Level Domains

A second-level domain is directly below a top-level domain in the domain hierarchy. It is the part of the domain name that comes right before the top-level domain. For example, in NameExperts.com, NameExperts is the second-level domain.

The second-level domain is usually a combination of words describing the business or service of the domain name owner – and it pays to match this to the name of your business whenever possible to strengthen your brand. In the above example, NameExperts describes the business of a professional domain name broker that helps customers to acquire valuable domains.

A second-level domain can include letters, numbers, and hyphens. Symbols are not allowed.

3. Third-Level Domains

The third-level domain, or subdomain, is the part of the URL that comes before the second-level domain. The most common subdomain is www., which refers to the world wide web. Third-level domains are not mandatory, so you can have a fully functional domain name without the www part.

Some website owners create third-level domains to represent a different section of their website. Examples include:

  • Shop.mywebsite.com refers to the e-commerce section of a website.
  • Blog.mywebsite.com refers to a blog attached to the website.
  • Support.mywebsite.com leads to the customer support section of a website.

Understanding Domain TLDs

A domain name is the most important property for anyone who conducts business online. Hence, it’s crucial to understand what they are and the different types of domain name extensions to use for a website.

The information above should help you figure out how to structure your domain, but if you need help, we’re experts at domain selection and helping you buy the perfect domain.

Domain Name History – How to Check and How to Stay Safe

Ever been tempted by an available domain name that seems too good to be true? Maybe it’s exactly that – with a hidden history that adversely affects its true value. In this post, domain name expert Joe Uddeme flags up the things to look out for when buying a domain name.   Researching domain history is important for businesses and website owners, especially when you wish to buy a premium domain. It’s like wanting to purchase a property and checking the record of its past owners, renovations, and sales history before signing the contract. If you don’t do your due diligence, you might find your dream property was a crime scene six months ago. The same can (kinda) be true of a domain name. You’ve arrived at the right place if you’re interested in digging deep into the history of any domain. This article will give you the relevant knowledge and tools to navigate a domain’s history – and help ensure there are no skeletons in your URL’s closet. Key takeaways Domain history is important – ignore it at your peril A hidden past can help you negotiate a lower price (if you still want it) Discover all the top tips and tools that will help you unearth a domain name’s past   Why Would Someone Want To Know A Domain’s History Domain name history is important in several cases, mainly when someone wants to acquire a domain. For example, you come across a domain you want to buy but don’t know the owner. Investigating the domain registration history can help you find the owner so you can begin inquiring about purchasing the domain. These are typical cases that warrant a domain history lookup: Finding A Domain Name’s Owner You might find a domain that looks valuable for your business, but the existing website has no official information to contact the owner. In that case, researching the domain name history can help you find the owner’s email address, phone number, physical address, or other contact information. Conducting Research Before Buying A Domain Due diligence is critical if you’re buying any domain. Checking the domain name ownership history lets you know its reputation with search engines, which can affect your website’s discoverability and brand appeal. This due diligence lets you know if the domain was previously used for any malicious activity, and you can immediately back out if so. Or, if it has certain questionable connotations you can live with and you feel your name/brand is strong enough to survive the domain’s hidden past, you can use its history to negotiate a lower price. Competitive Research Checking a competitor’s domain name history can reveal valuable information. Who registered the domain? How long has the website existed? How much was the domain acquired for? Has the domain ever been sold? These questions give great insight into your competitors, letting you know how to stand out and win customers.   Checking A Domain’s History The WHOIS database is the first place to check a domain name’s history. This public database contains the information collected when someone registers a domain name. You can use it to find relevant information about a domain name’s owner and operational history. WHOIS Lookup You can query information from the WHOIS database using any WHOIS lookup tool. This database is publicly available, so many websites allow users to type in a domain name and see every information related to that domain in the WHOIS database. Examples of such tools include WHOIS.com, Who.IS, and WHOIS.DomainTools.com. Type a domain into any of these tools, and you’ll see relevant information about it, including: When the domain was first purchased A WHOIS lookup always shows a domain’s initial registration date. This information gives you a clue of how long the website has existed. To illustrate, let’s perform a WHOIS lookup for NameExperts.com. We typed this domain into the Who.IS lookup tool and got the following information:

5 Things to Consider When Buying a Domain Name

Looking for some quick tips about securing and buying a domain name for your business? Here’s our expert guide to domain buying, covering everything from hidden fees to privacy protection.   Purchasing a domain name is an exciting thing for a new business, but there’s much more to it than simply finding the ideal name. Before you begin, there are a few things you ought to know. It’s always worth remembering that not all businesses selling domains (known as domain registrars) are the same. Some use tactics like hiding fees or promoting your data to earn more cash, which may have an enduring influence on your enterprise. In this post, Name Experts Director Joe Uddeme – a seasoned domain name broker – flags up some common things you should watch out for.   1. Look out for hidden charges As with any purchase choice, cost can be a big element. It is easy to be tempted into buying a domain at a really low cost. But don’t be fooled: a few domain registrars provide promotional pricing at an extremely low price but then hide a lot of fees in the contract, lock you in, and charge high renewal prices. Generally, be aware that registrars offering rock-bottom domains may have additional, less-than-ethical techniques to make money. These strategies include: Adding in hidden prices: Many registrars rely on the fact that most individuals do not read the fine print. Before you make a domain purchase, review the Buyer’s “Terms of Service” for any questionable terms, duties, or fees. Be sure to check what the renewal rates will be, and be certain you are only buying what you need and want. Making you pay to edit your WHOIS or RDAP listing: Watch out for registrars that charge an “administration fee” when you need to edit your WHOIS or RDAP records. Registrars will often try to “upsell” or “cross-sell” you items you don’t require. For example, they might recommend you purchase extra domain endings that are extraneous instead of helpful (for instance, .info or .co). Or, they might offer to package your domain with a bunch of other services you might never use. Charging transfer charges: Make sure the “Conditions of Service” don’t have “transfer-out” charges for moving your domain name to another registrar. These fees could be exorbitant and they violate ICANN policy (ICANN is the non-profit corporation that oversees the use of Internet domains). Beyond the cost, a few registrars make it nearly impossible to perform a transfer by making the transport procedure cumbersome and hard to navigate. It’s a good idea to check into how easy the transfer process is before deciding upon a registrar.   2. Protect your privacy Unprotected data is vulnerable to being mined by spammers and scammers. Start looking for domain registrars that offer privacy protection for free. Be cautious about dealing with registrars that charge a premium for “privacy solutions,” particularly any who offer to place their details on these registries instead of yours, which covertly gives them possession of the domain.   3. Guard your info Beyond failing to protect your personal data from public records, some registrars actively sell your information to third parties like marketing associations. Some registrars even mine the WHOIS database and then send false renewal invoices, getting visitors to unknowingly transfer their domains. Be certain to find a registrar that promises never to sell or misuse your client information for marketing purposes. 4. Focus on transparency Look for registrars that offer transparency in their pricing. You should, for example, be able to readily find your renewal prices, as well as the processes for transferring or canceling your domain name registration. Some registrars offer cheap registration during the initial purchase, but then charge flat-rate costs to renew your domain the following calendar year. They also might make it very difficult to cancel your order. Start looking for a registrar with upfront pricing info and terms of service to avoid surprises later on.   5. Differentiate support from sales Some registrars don’t have support staff but instead have salespeople who are trained to sell you add-on services you may not need – all in the guise of friendly customer support. Look for a registrar that offers courteous and professional support and help, not one that sees you as a cash register they keep trying to ring. With careful study before you opt for a domain, you can side-step some unfortunate traps and make sure your domain name — and your business – are in good hands for many years to come.   About the author Joe Uddeme is Director and Principal of Name Experts, one of the world’s top domain name brokerage services.

Understanding the Domain Name Scam

The bigger the domain name purchase price, the more attractive it is to scammers and fraudsters. Global domain name broker Joe Uddeme shares his top tips for staying safe when buying or selling premium domain names. It’s essential to understand the different types of domain name scams to protect yourself and your online identity. Domain name holders must be vigilant about renewing their domain names to retain exclusive rights. Domain name scams can be difficult to spot, but there are ways to identify them, such as recognizing phishing emails. One domain name renewal scam typically involves urgent phone calls or emails pressuring you to renew your domain names immediately and pay or risk losing your domain. This domain name renewal scam tries to trick people using phishing scams and deceptive tactics when registering names. Awareness and reporting are crucial to protect yourself. Be cautious of emails or letters that create a sense of urgency or threaten to cancel your domain name registration. Watch out for fraudulent domain renewal notices that may look official but are not. Domain registrations often come with options for renewal or transfer, so explore these to avoid falling for scams. Always verify the authenticity of the email or letter by contacting your registrar company directly. Be aware of deceptive practices by companies that send official-looking letters from a domain registry, urging you to transfer your registrations under false pretenses.   Protecting Yourself from Domain Scams Always use a secure payment method to pay for domain name renewal. Recognizing legitimate renewal notices is essential to avoid unnecessary fees and potential loss of domain ownership for the customer, so don’t ignore every email you received about your names. Just treat them all with caution. Verify the authenticity of the email or letter by contacting your domain registrar company directly. Scammers often exploit the relationship with your existing registrar by suggesting that a transfer is merely a renewal process. Monitor your domain name registration and renewal dates to avoid missing important deadlines. Scammers use various methods, including urgent phone calls and deceptive emails, to execute a renewal scam. Use domain locking to prevent illegal transfers. Domain hijacking is another threat that can be mitigated by this measure. Registration scams typically manifest through fake renewal notices, creating confusion and unwarranted financial pressure. Keep your contact information private by using a domain name privacy service. Scammers may trick owners through fake offers, exploiting confusion around domain registration and renewal. Fraudulent phishing scams often target website owners, too, using tactics to deceive them into believing they owe money or need to make changes to their domain or hosting services.     Understanding Domain Name Renewal Scams A Domain name renewal scam is a type of intellectual property scam or confidence scam that target the owner. These scams can result in financial loss for businesses and individuals. The financial loss can be substantial, affecting both small businesses and large corporations. Domain name scams can take many forms, including domain slamming, false offers to buy or sell domains, and fake trademark protection. It’s essential to understand the different types of domain name scams to protect yourself and your online identity. Domain Registry of America is an example of a fake trademark protection service. They contact the website owner claiming to have a trademark right or warning that someone else owns the rights to your name. Check your expiration date and make sure your domain information is protected so you don’t lose control of your asset. While you can’t technically buy a domain name forever, you can register and renew for extended periods. Domain name scams often involve unscrupulous domain name registrars attempting to generate revenue by tricking businesses into buying, selling, listing, or converting a domain name. These scams can be difficult to spot, but there are ways to identify scam tactics. Be cautious of emails or letters that create a sense of urgency or threaten to cancel your domain name registration. Always verify the authenticity of the email or letter by contacting your registrar company directly. Be able to recognize scammer tactics by paying attention to blog post and article updates. Customers should also consider adding two-factor authentication for all registered accounts, or hiring a domain name consultant for guidance. Definition of domain name scams A domain name scam is a fraudulent scheme where scammers deceive individuals or businesses into paying for fake registration services, overpriced renewals, or by impersonating legitimate registrars. It often involves phishing, domain hijacking, or misleading offers to trick victims into making unauthorized payments or losing control of their domain Importance of awareness and prevention Awareness is the first line of defense against domain name scams. The website owner must be vigilant and proactive in protecting their assets. This means being cautious of unsolicited offers, verifying the authenticity of emails and letters, and keeping domain registration information up to date. By understanding the risks and taking preventative measures, website owners can safeguard themselves from getting scammed. Regularly monitoring domain status and using secure payment methods for renewals are also crucial steps in prevention.   Domain Registry and Scams Domain renewal scams: fake notices and invoices Domain scams are a common tactic used by the scammer to trick the owner into paying for unnecessary services or transferring their site to a different registrar. These scams typically involve sending fake notices or invoices that claim the domain name is due for renewal. Often involving inflated prices, notices often appear to be from a registry or a legitimate company, but they are actually from fraudsters posing as an internet registry. Swindlers use various tactics to make these notices or invoices appear legitimate. They may include the domain owner’s contact information and registration details, creating a sense of urgency by claiming that the domain names will expire or be lost if the renewal fee is not paid immediately. They may ask for you to renew your domain and pay an exorbitant fee. This pressure can lead the holder to act hastily without verifying the authenticity of the notice or link. They may also try an inflated price on the renewal scam for your website or use a scare tactic and tell you your name is about to expire if you don’t pay a fee. To avoid domain scams, website owners should be cautious of unsolicited notices or invoices. Always verify the authenticity of the sender by contacting the current registrar directly or checking the domain name holders registration information online.     Domain Scams – How to Stay Safe To protect yourself from domain scams, it’s crucial to be vigilant and take proactive steps. Here are some tips to help you avoid falling victim to domain scams: Keep your domain registration information valid, up to date and secure so it never expires. Simply renewing ahead of time. Set a calendar reminder to be a step ahead Be cautious of emails or letters that create a sense of urgency or threaten to cancel your domain name registration. Verify the authenticity of the email or letter by contacting your domain registrar or reseller directly. Use secure payment methods when you register and renew your site or domain name. Avoid Mail that contains your physical mail address. Address customer concerns by contacting customer support. Monitor your domain name registration and renewal dates to avoid missing important deadlines. Consider adding auto-renew as a double check for registering your asset before it expires. Use domain locking to prevent unauthorized transfers of your registered assets. Keep some money in the registrar account in case you have an issue with your credit card when you pay. Keep your contact information private by using a domain name privacy or proxy mail service. By following these tips, you can reduce the risk of falling victim to domain scams and protect your online website identity for your domains.   Reporting Domain Scams to Your Domain Registrar If you suspect that you have been a victim of a domain scam, it’s essential to report it to the relevant authorities. Here are some steps you can take: Report the scam to the Federal Trade Commission (FTC). Share the information about the scam on social media to warn others. Use the social media links provided to share the post. Report the scam to your domain registrar company such as Network Solutions. Contact the Internet Corporation for Assigned Names and Numbers (ICANN) Complaint department and let them know about the letter or email. File a complaint with the Better Business Bureau (BBB) if the scammer is a business. By reporting domain scams, you can help prevent others from falling victim to the same scam and bring the fraudsters to justice.   About the author Joe Uddeme is Director and Principal of Name Experts, one of the world’s leading domain name brokerage services.
