The Internet Corporation for Assigned Names and Numbers, or IANA, divides TLDs into three official categories: gTLDs, sTLDs, and ccTLDs. You can find a list of all active top-level domains in the IANA root zone database .
Generic Top-level Domain gLTD
These are probably the top-level domains you see often. Generic top-level domains are also what users expect to see. Some popular gTLDs are:
om
et
rg
While these may be called "generic," they can still tell you a lot about the type of website you're visiting. "om" stands for "commercial," "net" stands for "network," and org is short for "organization."
Some companies have made their gTLDs more specific. In 2011, companies and organizations were first allowed to register their own gTLDs, which is why you can now visit sites like:
oogle
.amazon
.apple
We'll cover country-based top-level domains further down azerbaijan mobile database in the ccTLD section, but we'll point out here that geographic gTLDs or GeoTLDs do exist. These gTLDs are associated with a specific geographic region. They are not automatically geotagged like ccTLDs are. GeoTLDs include the following extensions:
.berlin
.amsterdam
.paris
Geographic gTLDs are handy because they indicate the city you're located in or the region you serve. They can also make you more appealing to local readers.
Sponsored Top-Level Domains sTLDs
Sponsored TLDs are TLDs that are specifically sponsored by groups such as businesses and governments. Some examples include:
ov
.museum
.edu
There are far fewer sTLDs than gTLDs. The IANA database currently lists over 1,200 TLDs as “generic” and only 14 as “sponsored.” This is partly because you have to meet some pretty strict criteria to use an sTLD.
