I used to have a Virtual Server on a unique IP, then I deleted that Virtual Server and I want to now re-use the IP, but I find that I am unable to use that IP any more.
Firstly it still shows up in the System Information > IP Address Allocation as being linked to the domain that no longer exists (which seems odd). Secondly the IP does still show up as a Virtual Interface under Webmin > Network Configuration > Network Interfaces.
I now want to move one of my Virtual Servers from the Shared IP over to this (now free) unique IP but when I go to Server Configuration > Change IP address, this IP does not show up as available.
What is the correct way to do this?
