Why are name servers important to my domain name and e-mail?

When a Internet domain name is registered, part of that registration information is to tell the world which name servers are in charge of managing the DNS information for that domain. The entity that manages the DNS information for a domain name basically controls the addresses to where all names in that domain point. All the other DNS servers in the world know this one particular server is the one to ask where www.teamITS.com points. The name servers for a domain also control where the e-mail for that domain is sent.

When a company changes web hosting providers, the name servers for the domain usually must change to those of the new web host, so the new hosting provider can control the domain and manage web, e-mail, and other services.
