[Phpip-support] Newbie - few quesitons about prefixes/CIDR

[<php...@li...>]

Hi,

Just found phpip which seems to be almost exactly what the doctor 
ordered in terms of a simple IP management tool.

My only gripe (which could be me using it wrong) is the system seems to 
presume a "Prefix" is a /24 (class C). Why?

I ask for two reasons:

Lets say my ISP allocates me 150.10.10.0/24. I may want to use that 
allocation on two separate networks. I'll still manage the entire /24 
but i'll actually want it dividing into two /25 "Prefixes".

Similarly if i allocate 10.10.0.0 /16 to internal hosts i may have a 
site with 300 that i want to allocate a /23 within that /16 allocation.

If there is a way of doing this please let me know, as in every other 
way (except for a maybe search all fields option) it's perfect. Thanks.

Nick
