looking for guidance

[Jeff Donovan]

greetings,

Im stuck at a cross road in my current project. I am switching ISP's. 
I am hosting primary DNS for a batch of IP addresses that I will need 
to give back to my old ISP. This requires me to re-configure my DNS 
server.

Simple enough,..replace the old with the new right?
well,.here is where I get muddy. I will still have service through my 
old ISP until I can get all of my old addresses physically switched 
to the new block(s).
So i may still need to run DNS for these old addresses AND for the 
new addresses.

ok,..insert the new and don't remove the old right?
But what do I do about the naming convention. Where the new addresses 
take the place of the old, the name stays the same. should I have 
multiple names per IP?


@@spinning wheels@@

I would like to hear your comments

thanks
