That depends. Do you have a whole class C subnet, or only part of one? If you have a full class C, is it part of a larger block that they own, or is it delegated individually to them by their upstream provider? If it is delegated by itself to them, they would have to talk to their upstream provider about redelegating it directly to you; they may not want to do this, and their upstream provider may not want to do this. The best alternative in this case is to have them continue to be authoritative, but have their servers act as secondary for your server. If you have a full class C, and it is part of a larger block owned by your ISP, they should be able to delegate it to you without breaking a sweat. If you have a part of a class C, refer them to RFC 2317 for instructions on how to delegate a "classless" subnet. It takes a bit of effort, but once you get the hang of it, it's conceptually easy. ____________________________________________________________________ Chris Buxton Men & Mice cbuxton@menandmice.com http://www.menandmice.com
