Can someone check that my RDNS is working?
« on: November 24, 2009, 11:51:21 AM »

Can someone check to see that RDNS is working for my hosts?  If I check it from an IPv4 only client outside my network, I don't get an answer, but I do see a bunch of traffic passing through my firewall intended for my DNS servers from HE

These are the results I get:

Do I need to have IPv6 connectivity on the host I'm checking this from?

But obviously I have IPv6.  IPv4 only resolvers won't be able to contact selma or patty to resolve your RDNS until/unless you add IPv4 addresses to those servers, or add a 3rd slave that has an IPv4.
