This article is the beginners guide into the realms of Top Level Domains, which will answer all your questions on what is a TLD.
If you have ever stared at the “TLD” abbreviation and wondered what it is. Wonder no more – here is the answer.
What is a TLD?
Top-level domain (TLD) refers to the last segment of a domain name or the part that follows immediately after the “dot” symbol.
There are 5 types of TLDs:
- Generic (international) Top-Level Domains (gTLD) – com, edu, org, net, etc.
- Country-Code Top-Level Domains (ccTLD) – co.uk, ca, au, etc.
- Sponsored Top-Level Domains (sTLD) – museum, aero, etc.
- Infrastructure Top-Level Domains – .arpa
- Test top-level domains (tTLD) – test
What Is the Purpose of a TLD?
TLDs serve as the instant notification to see what the domain is all about.
For example, when you see “.edu” domain it’s an instant reminder that the page belongs to a university or another educational institution.
What Are the Different TLDs?
If you are looking to find which TLD will better suit your business here are all the categories explained in detail.

Infrastructure Top-Level Domain
Under this category, there is only one TLD – .arpa
This TLD is used exclusively for technical infrastructure purposes.
While the name was originally the acronym for the Advanced Research Projects Agency (ARPA), the funding organization in the United States that developed one of the precursors of the Internet (ARPANET), it now stands for Address and Routing Parameter Area.
Test top-level domains
The Internet Engineering Task Force reserved the DNS labels:
These TLDs cannot be installed into the root zone of the Domain Name System.
The reason for reservation of these top-level domain names is to reduce the likelihood of conflict and confusion. This allows the use of these names for either documentation purposes or in local testing scenarios.

To re-cap, each TLD includes an independent registry controlled by a specific organization. Which is managed under the guidance of the Internet Corporation for Assigned Names and Numbers (ICANN).
