Domain Name : What Do The Various Domain Extensions Mean

What are Domain Extensions and How do I Choose a Domain Extension?

Everyone knows .COM, the unrestricted domain extension for companies or commercial enterprises that is the most recognized TLD on the web. Most people in our country also recognize .CA, the ccTLD that represents Canada.

But what about all the other domain extensions out there? .ORG, .NET, .MOBI, .TV, .TEL, .BIZ, in fact there are over 280 different domain extensions delegated globally. What do they all mean and whats their relative importance to Canadian small businesses? Its important that a small business understand what its options are for developing and marketing their brand in the online arena.

According to the latest Domain Name Industry Brief , the first quarter of 2010 ended with more than 193 million domain names registered worldwide, an increase of 11 million registrations or 6% from 2009.

    The Most Popular Cctld Domain Extensions

    Verisign claims that the most popular country-specific domain extension is .tk, which the official domain of the group of atolls, Tokelau. This is according to their survey data . Although only about 1,500 people live in the territory, there are about 27.5 million .tk domains. Many website operators resort to a domain from Tokelau, as these can be registered free of charge and in a relatively simple manner. In contrast, the domains of North Korea are not exactly easy to come by. The secretive state seems to use only about 28 domains.

    Because .com is used so widely in the USA, the .us ccTLD doesnt appear on this list. This isnt really a reflection of how active US citizens are online though, as about 88.5% of the US population use the internet, according to figures from statista. Thats a huge number within a huge population! Compare this to China, which ranks second on the above list: only 54.3% of the population are using the Internet, according to the CIA.

    How Memorable Are Different Domain Extensions

    An important factor for any URL is how easy it is to remember.

    The question we wanted to answer is, are people more likely to remember URLs with some TLDs over others?

    As you can see, yes they are:

    The .com domain extension comes out on top here again, with a 44% memorability score.

    That means people correctly remembered the .com URL 44% of the time.

    Second place goes to .co again, but this time its a wider gap: with its 33% memorability score, .co is a full quarter less memorable than .com.

    Comparing .com to its two traditional main competitors, .net and .org , you can see its not even close.

    Interestingly, .biz has a score of 31% which is actually better than .us, .io, .net, and especially .blog .

    I was also surprised to see .net perform so much worse on this test than .biz.

    However, it makes sense considering that mental categorization is a major part of how memory works.

    Perhaps people naturally put the .net TLD in the same mental category as .com: a general, fairly common TLD thats often used for commercial sites.

    However, since .com is the most dominant TLD in that category, .net often gets mis-remembered as .com .

    On the other hand, .biz may not fit into the same mental category as .net and .com.

    Think about it: if you see,, and, doesnt the .biz version jump out at you a little?

    That may be why .biz domains are more memorable despite being less trustworthy than .net ones.

    Everything You Need To Know About Domain Extensions

    6 Clever Uses of Domain Extensions

    Most people know a little about domain extensions. For example, you would be hard pressed to find someone that didnt know what .COM is. However, did you know that there are over 1,500 TLDs as of December 2018? Furthermore, .COM and .NET account for 50% of all domain name extensions registered worldwide!

    To really understand what domain extensions mean and where they came from we have to drop back a little and take a look at the Internet and how it played a part in domain name extensions. We will also take a look at the domain extensions list and see how many there actually are, what they are used for, and what custom domain extensions mean.

    When People Remember The Top

    This last factor is an interesting one:

    When people remember the URL almost correctly when they remember the brand name but put the wrong domain extension at the end which domain extension do they say?

    This helps us see how much of a bias people have in favor of each TLD.

    For example, if the correct URL was mattressrankings dot net but they misremembered it as mattressrankings dot com instead, that would count as a point for the .com TLD.

    The results of this test show an even bigger difference between .com vs other domains.

    Heres the data:

    First place again goes to .com, by far.

    Out of all the wrong-but-almost-right answers, 57 of them said .com instead of the correct TLD. Thats 3.8 times more often than the next highest, .org.

    This is strong evidence that .com domains are still thought of as the default.

    When people arent sure which TLD a URL uses, theyre much more likely to guess .com than anything else.

    The distant second place goes to .org, which people guessed only 15 times: 26% as often as they guessed .com.

    Not shown on the chart above is the domain suffix, which received two guesses but wasnt a subject of this study .

    Key takeaway: People are 3.8 times more likely to assume a URL ends in .com than in anything else.

    Signatures And Zone Signing

    To limit replay attacks, there are not only the normal DNS TTL values for caching purposes, but additional timestamps in RRSIG records to limit the validity of a signature. Unlike TTL values which are relative to when the records were sent, the timestamps are absolute. This means that all security-aware DNS resolvers must have clocks that are fairly closely in sync, say to within a few minutes.

    These timestamps imply that a zone must regularly be re-signed and re-distributed to secondary servers, or the signatures will be rejected by validating resolvers.

    Top 7 ccTLD emoji domain extensions

    One of the oldest TLDs in the world is still the most popular domain extension after more than 30 years: .com. Originally intended as an abbreviation of commercial and planned only for companies, many users now associate .com domains with websites in the USA. This is for good reason, as the domain extension .us, which was actually intended for the USA, isnt used as much as .com, although .us is on the rise for government websites, alongside .gov.


    This ranking is taken from Analysis by This service provider measures published websites and tries to filter spam websites from its statistics. This therefore sometimes results in different statistics to other publications. Another source worth checking out is the Domain Name Industry Brief from Verisign, the operator of the .com domains.

    No matter which statistics you look up, more than half of all Internet addresses have the extension .com. Also high up in the rankings are the other two generic top-level domains .net and .org. Like .com, these have been around since 1985. The other domain extensions in the top 10 are primarily country code TLDs , which are country-specific. .us isnt high up on the list at all possibly because most websites in the USA will use .com.

    What Is A Domain Name Extension

    Prior to the early 1980s, in order to visit a host on a network, the user would be required to type in an IP address, which is a numerical string of code consisting of digits and periods. Computers on this early network were able to communicate and locate one another using these numerical Internet Protocol Addresses.

    Since, at the time, there were not many computers on the internet, this system was manageable. With that said, it was still not easy nor efficient because you needed a way to keep track of every single IP address in the network. If you did not have the IP address, there was no way to visit or communicate with the desired website. An early internet user could not query a site, or go surfing the web as we do today, rather you were restricted to the sites that you already knew how to locate.

    Basically, it was equivalent to having a map of a foreign country, but that map only listed the directions to a handful of cities. This limited where you could go and made discovery outside of the context of the given directions impossible. Thankfully, computer scientists of the Internet Engineering Task Force gathered together and decided to simplify the system. has over 300 domain extensions to choose from to help set your website apart from the rest. It all starts with a great domain.
