Reverse DNS troubles
Posted on 2003-11-02
I'm having trouble getting our network to do reverse-dns lookups correctly. I'll try to explain a bit.
We registered two DNS machines at Network Solutions. We set up our master and slave machines, and can do forward lookups with no problems. We are using a big ISP to provide bandwidth to us- through the router that they provided. I am wondering if they need to set us up as authoritative for our domain name. The reason that I draw this conclusion is that I CAN do reverse lookups on the local area. However, outside the router and from another network, I cannot. My point is that I think that the host name is not getting resolved into an IP because of something between an outside network and my DNS machines. In short;
-inside LAN (reverse DNS lookups work)
-outside LAN (reverse DNS do NOT work)
