Creating or updating a dns delegation

Rated 4.96/5 based on 555 customer reviews

A subdomain is technically defined as when you assign a different section of name servers for part of a domain. Creating “sub.” on a different group of name servers than “” would be creation of a subdomain.

In contrast, “ is a record with the name of “www” within the domain “”.

Each name server host name must end in a dot (.) to keep your domain name from being appended to the end.
