I believe your server already has one IP address configured for eth0.
When you now create a new site and put a new IP address, the GUI will automatically create eth0:0 and will associate the new IP as
an Interface Alias to Eth0. When an "alias" IP becomes free (i.e.: no more sites are using it), then it will be removed automatically.
