We do it all the time to point our client's web sites at the web server.. that way, we don't break RFC by using a single IP address and virtual hosting on it. RFC says (somewhere, don't remember which one) forward and reverse have to match, so having the following would be invalid: web.real-time.com. A 10.0.0.1 10.0.0.1 PTR web.real-time.com. www.domain1.com. A 10.0.0.1 www.domain2.com. A 10.0.0.1 you are SUPPOSED to do it the way he was talking about above: web.real-time.com. A 10.0.0.1 10.0.0.1 PTR web.real-time.com. www.domain1.com. CNAME web.real-time.com. www.domain2.com CNAME web.real-time.com. This also makes it a helluva lot easier if we ever switch the IP of our web server. -- Nate Carlson <natecars at real-time.com> | Phone : (952)943-8700 http://www.real-time.com | Fax : (952)943-8500
