A top-level domain (TLD) is the first stop in the DNS hierarchy after the root zone. To put it another way, a TLD is everything that comes after the last dot in a domain name. The TLD in the domain name 'google.com', for example, is '.com'. '. org' and '. net' are two more prominent TLDs.
The last section of a domain name, or the component that comes after the "dot" symbol, is known as the top-level domain (TLD). The ".com" component of the internet address https://www.google.com is an example of a TLD.
The Internet Corporation for Assigned Names and Numbers (ICANN) is in charge of keeping track of all current TLDs and managing domains and IP addresses on the internet. The Internet Corporation for Assigned Names and Numbers (ICANN) recognises three types of domain suffixes.
infrastructure domain name at the top level (ARPA)
top-level domains (gTLDs) (gTLD)
Top-level domains with a generic restriction (grTLD)
top-level domains (TLDs) that are sponsored (sTLD)
The top-level domain is the highest level in the internet's hierarchical Domain Name System, aside from being a component of a website URL (DNS). As a result, it is critical for a website to not only work but also to appear credible to potential visitors.
