I'm not sure what you're saying there, I'm afraid. I tried pointing dig at
localhost to see if bind knew what to do with it. Wasn't that legal or
sensible?

Yes, exactly :-(
0 TTL ? I don't know where you got that. I don't see it in my responses. Is
it a clue?

named.ca is straight off the internic site.

I don't know what the firewall would do. I have a Cisco 678 DSL router with
NAT running to map the ports to the right machines on my private LAN, but
that's about it. On the subject of firewalls, though, I added the
"query-source address * port 53;", only because I think I'm supposed to.

I'm ploughing my way through O'Reilly "DNS & Bind", but I can't find what
could be causing this. I suspect it has something to do with translation
between the private domain and the pblic one, but O'Reilly is rather thin in
dealing with that area, so I don't know what to look for.

One question: while I'm making queries from my own LAN, using my own DNS
server, will bind ignore the entry on granite canyon? They're still listed
as masters until I get my own server going.
