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.l...@gmail.com ReplyTo: Gregory Hicks Subject: Re: Recommendations for reverse DNS providers Sent: Mar 17, 2010 5:11 PM > Date: Wed, 17 Mar 2010 16:08:03 -0700 > From: Mike Lyon <mike.l...@gmail.com> > > Hello, > > I am curious what folks recommend these days for reverse DNS > providers?
