About Top Level Domain

The Top Level Domain represents the couple of letters that can be found after the final dot of a web address. The acronym for Top Level Domain is TDL. A Top Level Domain can help users to recognize the website associated with the web address, the area the company originates or the purpose of the organization.

Types of Top Level Domain

Top Level Domain is classified into some categories. 

The first one is Generic Top Level Domain (gTLD) and it includes all domains that are not associated with a country (for example: .com, .org, .net). 

The second type is Country-Code Top Level Domains (ccTLD) and it contains all domains that are identified with a geographical location (for example: .de, .dk, .nl). Internationalized country code top-level domains (IDN ccTLD) represents a subcategory of ccTLD and refers to non-Latin character sets. 

Another type is the Sponsored Top Level Domain. These domains are developed and funded by private agencies or associations which set and implement rules that limit eligibility to use the TLD.

The Infrastructure Top Level Domain represents another category of Top Level Domains (with one domain: the Address and Routing Parameter Area). It is managed by Internet Assigned Numbers Authority on behalf of the Internet Engineering Task Force.

Another category used when we talk about Top Level Domain is Test Top Level Domains (tTLD). These domains were installed under .test for testing purposes in the Internationalized Domain Name development process.
