In short, domain name delegation is the process of assigning authority over a domain name to a specific name server, allowing users to access websites using that domain name.
Domain name delegation refers to the process of assigning authority over a domain name to a specific name server. This process is necessary because domain names are organized in a hierarchical structure, with each level of the hierarchy controlled by a different authority.
For example, the top-level domain (TLD) ".com" is managed by the Internet Corporation for Assigned Names and Numbers (ICANN), while the second-level domain (SLD) "example" in the domain name "example.com" is controlled by the company or individual who owns the domain name. When a user types "example.com" into their web browser, the browser first needs to find the name server that has authority over the "example.com" domain. This is where domain name delegation comes into play.
During the domain name delegation process, the owner of the "example.com" domain would provide the IP address of their name server to the TLD registry (in this case, ICANN), which would then update its records to include the new name server. This would allow the name server to be contacted when a user tries to access "example.com," and the name server would then provide the IP address of the website's server so that the website can be displayed to the user.
