Same general practices for forward dns apply to reverse as well - you should have a secondary on a separate netblock/provider/connection from the master nameserver. Also depends on what's going to be on the netblocks your hosting rdns for. If its a bunch of mail servers, rdns is kinda important from an anti-abuse perspective. Same with dynamic clients. ------Original Message------ From: Gregory Hicks To: nanog@nanog.org To: mike.lyon@gmail.com ReplyTo: Gregory Hicks Subject: Re: Recommendations for reverse DNS providers Sent: Mar 17, 2010 5:11 PM

Hello,

I am curious what folks recommend these days for reverse DNS providers? UltraDNS? FreeDNS?

BIND No difference between a forward and reverse zone to BIND. Both work well...

Thank You, Mike
