Set in 2.4, perhaps it will be needed soon.

Hi,

I just ran into this.
Currently you need to make heavy abuse of regex matches to implement subnet calculations.

It is feasible for dealing with small numbers of networks but i.e. when considering doing this for 1000 or 10000 subnets it gets really awkward and it's very hard to automatically generate.

Now, to make it worse:
We've just established it's possible to add them using regex. But honestly: It's pretty impossible to maintain and thus it should really be a builtin comparism.

Please keep in mind ipv6 on this one since it'll be even more needed. I don't think we want to assign a million+ ip range for any single dmz network...
