Reverse DNS is a hierarchy like DNS (you only have to reverse the IP address and append "in-addr.arpa." to it). When a name for your IP-address is looked up, it queries for: (1.) arpa. (2.) in-addr.arpa. (3.) 24.in-addr.arpa. (4.) 9.24.in-addr.arpa. The zone "9.24.in-addr.arpa." is handled by ns1/ns2.home.net, they are the ones responsible for your IP address. The search ends here, even if you run your own DNS it would never be queried for this reverse lookup (unless @Home would delegate it to you, which will never happen..) -- Walter Hop <walter@binity.com> Updated contact information: http://www.binity.com/~walter/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
