If one was to do it with BIND, the owner of the /24 (or better) creates individual delegations for each IP address. The new delegated server serves up one zone per IP address. That's how they used to do it before RFC2317, and the reason RFC2317 was written. It's possible, but with BIND it is a PITA, that's all. (Of course with tinydns, it's just as easy either way, but that's a bit OT). :) I wondered how come some ISPs refused to do anything but RFC2317 style delegation... Perhaps they too thought it was impossible. -- Greg White To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
