[Resolved] Change Assigned Domain IP

[weaselball]

Sorry is this is covered in the forums somewhere, but I did a search and either can't find it, or I'm searching for the wrong thing.

I need to change the IP address of a domain. I've added the new IP to the control panel, and going to the domain details of the user in question, I can see which IP they're assigned, but I see nowhere to change it. Am I just blind?

I saw in the wiki how to change the main system IP, but that's not what I need to do. I just need to change one domain.
