Specifically, in one of the examples, J. de Boyne Pollard writes: You create a "zone" file for a suitable superdomain that encloses all of the relevant reverse lookup domains (the easiest option being to just use "in-addr.arpa."): $ORIGIN in-addr.arpa. @ 1D IN SOA ns hostmaster.in-addr.arpa. ( 0 3600 120 3600 3600 ) @ 1D IN NS ns Which, I would agree with Roy Arends, isn't a good idea. Though I still think it's possible to do reverse delegation of individual IPs using NS records (just as one delegates individual class-Cs using NS records) and thus avoid RFC 2317's CNAMEs. I need to play with this myself one day. But this is way off-topic now.... -- David Siebörger drs-stable@rucus.ru.ac.za To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
