DNS Woes
Mark wrote in
today to say that reverse lookups for my domain weren't working properly.
And lo, nslookup
was having a hard time finding the machine it was
running on.
At first I thought maybe it was a problem with what I was trying to do with
the latest version of bind.
You see, I set things up such that I
control the reverse lookup on the 32 IP addresses
Atlantic Internet
provides me.
This is done via an interesting hack. For the appropriate
in-addr.arpa
file, I have:
0 IN NS linus.slab.conman.org. 1 IN NS linus.slab.conman.org.
And so on for the 32 addresses I've been assigned. Then, for the namesever here in the Computer Room, I have:
1 IN PTR isdn.slab.conman.org. 2 IN PTR area51.slab.conman.org 3 IN PTR linus.slab.conman.org. 32 IN NS ns1a.aibusiness.net. 33 IN NS ns1a.aibusiness.net. 253 IN NS ns1a.aibusiness.net. 254 IN NS ns1a.aibusiness.net. 255 IN NS ns1a.aibusiness.net.
I've also set the nameserver to think it's a master for the
in-addr.arpa
zone I appear in.
So anyway, I thought the latest version of bind
wasn't liking that.
And it turned out that was true, to a degree.
There is no such TLD
as .apra.
Stupid typo.
