I was going to get a cobalt server, and have several domains i am going to put on it. However, I don't like the idea of hosting the DNS on the server, as if it goes down, then so does DNS.

Is it possible to have the host set up one domain on the server, and then point the rest of my domains (ie. hostnames/mx settings) to the box and still be able to set the individual domains up.

For instance, right now I've got one shared account, and several domains with an outside DNS company. They all point to one IP. Is this possible to just redirect the settings from the DNS provider?

Yep. The RaQ handles name based hosting well.

(I had to put something other than 'Yep.')
