For some reason, DNS stopped working in my home network. I'm not sure when this started, I don't test it every day. Basically, I'm using bind in my home network for local DNS resolving. When I ping a host from my DNS server (Hermes) it works fine and shows the proper IP. But if I ping from any other PC, it does not work. I don't understand why this isn't working. I don't remember changing anything, other than setting up a few DHCP reservations, which I wouldn't think would effect DNS.
When I ping a host from any other PC, I get:
That looks like it's the ISP domain that is responding and not my local PC.
64 bytes from hit-nxdomain.opendns.com (18.104.22.168): icmp_req=2 ttl=56 time=29.4 ms
Here is my /etc/bind/net.localnet:
; dns zone for for localnet
; any time you make a change to the domain, bump the
; "serial" setting below. the format is easy:
; YYYYMMDDI, with the I being an iterator in case you
; make more than one change during any one day
