First thing is to update your zones to cut the TTL down to a few hours or even minutes. You need to do this so that the current TTL expires *before* your intended move. If your current TTL is 7 days, you're too late ;-( Just before moving, issue the NS record updates with your registrar. Hopefully you use a registrar that lets you do this dynamically via the web. It usually won't take effect for at least a day as the top-level zone files are not updated but once per day, I believe. If you have secondary DNS servers that are outside your network that is moving (this is a prime example of why this is recommended), be sure to update your DNS server and have the secondary fetch a copy of the new zone file. Then move the network, bring it all up again, and you should be good to go. If your TTL is shorter than the move time only some *really* broken remote sites won't notice in time. -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Vivek Khera, Ph.D. Khera Communications, Inc.
