Search Again: Re: Help! I''m a newbie... From: Sean Stephens Date: Wednesday, May 2, 2001 Time: 2:32:08 pm Thanks andrew and chris, you are magnificent Still confused on some things though (I've set it all up and filled out the network solutions form to change my nameservers IP address and hopefully it will all come out in the wash) Question: my old QDNS (and the examples in the QDNS manual) have servers called ns1.xxx.com, whereas my new one contains my new IP address. What I mean is, when you attach to a server using the remote manager software, the "server" in the zone view or server view is an IP address and NOT in the form of my name server. Does this matter? How do I change it if not? I assume that it will work as long as I have the "master server" box with a reference to the ns1.xxx.com under each record. Then, (if I understand it), this is the way it will work (correct me if I am wrong)... 1) Some guy types in "www.xxx.com" 2) His dial up account searches for "xxx.com" at one of the big 13 servers, and is told to go to my server IP address. 3) QDNS gets the request and tells him to look under the record for "xxx.com" where it finds another A record called "www.xxx.com" and tells him it is on the IP address (actually on the same computer) 4) The server serves him the site. Where does the reverse PTR lookup come in? Does it even matter? Also, do I need to go to network solutions and change every single URL to point at my name server? Or simply changing my nameserver's IP fixes them all for me?
