Support for range expansion when creating IP addresses

[makpe]

Is it possible to add feature to Add IP addresses like 192.168.1.[1-254]/24 same works with device Interfaces?

Basically I like that when you create new prefix it should automatically generate all possible IP addresses to specified prefix. Easier to see free addresses under prefix IP addresses list without description.

Range expansion would be nice. You don't want to automatically create every IP because every IP probably isn't in use.

I noticed this on some commits, is this feature getting close? Very excited for it as well.
