This is actually quite doable, you just need to have a clued isp[1] who sets up a nifty little forwarding trick in the reverse DNS. Here's an exmple of how my old ISP did it: net152 ns kitenet.net. 153 cname 153.net152.200.144.198.in-addr.arpa. 154 cname 154.net152.200.144.198.in-addr.arpa. 155 cname 155.net152.200.144.198.in-addr.arpa. 156 cname 156.net152.200.144.198.in-addr.arpa. 157 cname 157.net152.200.144.198.in-addr.arpa. 158 cname 158.net152.200.144.198.in-addr.arpa. I then had to set up a zone on my dns server (kitenet.net) called net152.200.144.198.in-addr.arpa just like I would have for 200.144.198.in-addr.arpa if I had had the whole class C. It abuses bind horribly, and takes a lot of cname records on the ISP's side, but it works. -- see shy jo, whose reverse DNS doesn't resolve properly right now, horrors! [1] Well, I've had 3 very good isp's out of ~15 total, and only one was clued enough to know how to do it, so..
