Top-level domain (TLD) “is the last segment of a domain name, or the part that follows immediately after the “dot” symbol. TLDs are mainly put into two categories: generic TLDs and country-specific TLDs. The Internet Corporation for Assigned Names and Numbers (ICANN), is the organization that coordinates domains and IP addresses for the internet.”
A top-level domain recognizes an its objective (business, government, education), its owner, or the geographical area from which it originated.
ICANN recognizes the following types of TLDs:
- Generic Top-Level Domains (gTLD): These are the most popular types of TDLs. For example, “.edu” for educational sites and .”com” for commercial sites. These types of TLDs are available for registration.
- Country-Code Top-Level Domains (ccTLD): Every ccTLD recognizes a specific country and is generally two letters long. For example, the ccTLD for Australia is “.au”.
Some of the TLDs and their explanations are as follows:
- .com – Commercial businesses
- .org – Organizations (generally charitable)
- .net – Network organizations
- .gov – government agencies
- .mil – Military
- .edu – Educational facilities like universities
- .uk – United Kingdom
- .th – Thailand
- .ca – Canada
- .au – Australia
