Delegating in-addr.arpa for subnetted address space

[thorin at digitalvoodoo.org (thorin)]

Have a quick question and I hope someone Can point me in the right
direction.

My ISP has allocated a /28 (255.255.255.240 - 16 addresses) for my use
here.
Forward lookups work like a charm and are replicating to the slaves as
planned.

However, I have the need for reverse lookups to resolve and was
wondering if anyone has tackled this before in a subnetted environment.
I'm assuming I'll have to call my ISP (UUNet) and ask them to delegate
my portion of the address space before any of my modifications will take
effect - but I want to make sure I'm not missing something obvious here.
