Changing a running IP

[ikaRus]

Hi,

I have a test system ready to be deployed.

One thing bugs me.

I am trying to change one of the machines IPs, in preparation to what I'll have to do when I deploy this machine.

The IP belongs to a reseller, and holds a single test domain.

I have created another test IP on the machine (same domain name) and tried to remove the old IP.

I got an error msg stating that I can not remove this IP because it has a domain it belongs to.

Now this machine has ~30 secondary IPs that will need to be changed once the machine goes into the real world.

Not to mention the fact that IPs (even static) are quite dynamic :-) I've seen this more then once where my ISP gave me 1 a month to change IPs.

Please advice.
