Normally, when you move a server from one subnet to another, then it's address will change (since the prefix changes) and you should update the DNS accordingly as Francis noted in his email.
What Neeta is referring to is using Mobile IP to treat the server as "visiting" it's new subnet (where it would have a care-of address) and would thus be able to keep using its old address (called the home address) on the old subnet. Unless you expect the server to be moving back and forth fairly often, this is not really a good idea. Using Mobile IP incurs extra overhead and also requires the presence of a home agent on the "home" subnet. In most cases, you'd be better off just updating the DNS with the new address of the server on its new subnet. --Brian > -----Original Message----- > From: Neeta Srivastava [mailto:[EMAIL PROTECTED]] > Posted At: Thursday, September 27, 2001 05:07 > Posted To: IPv6 Users Mailing List > Conversation: IPv6 Addressing > Subject: RE: IPv6 Addressing > > > what I understand is when a permanent address machine move to > some other location its prefix will change accordingly.
