I have set up a Bind9 DNS server on my development VM which is running Debian Wheezy. My addresses resolve from my host machine (Win7) to my dev VM, and I can ping from there. Internally on the VM, I can ping my names (www, share, my_name, etc.) and it resolves to the correct ip (11.11.11.11). But when I ping my full FDQN (www.app.dev), it resolves to localhost. This is not true for my_name.app.dev, only the CNAME entries in my db.app.dev file in my /etc/bind/ folder. So if I ping www, resolves to 11.11.11.11, www.app.dev resolves to 127.0.0.1. Pinging www.app.dev or just www from outside the DNS VM resolves fine. Is this expected behavior or am I missing something?
Here are the files I think you want. I added resolv.conf in case there's something wrong there.
