Name Zone is a site that offers secondary DNS services to small domain and web site owners. We do offer daomain registration and web hosting but our primary focuse is secondary DNS.

Well, you don't have to have secondary but it really is a good idea. A secondary functions as a backup. Chances are your primary, if setup correctly, will not go down but if it should people will not be able to get to your webserv and, more importly, your email will not get deliverd. Modern mail servers, before they deliver email, do a forward and reverse lookup on your mail server. If either part of that lookup fails the mail server will reject the email. A fully functioning secondary DNS will prevent that.

We recommend Bind 9 or greater. Bind, which ships with FreeBSD and most Linux distros, is the defacto name server on the Internet. We use Bind 9 so our secondary update mechnism is based on bind 9.
