Hi everyone!
I am having issues with my bind server setup. When I try to resolve the
PTR for 130.248.154.166 or 172.82.233.25, I will get the proper result
only after a few tries so. After that, resolving will work. Resolving
with 'dig +trace' will yield the proper result on the first try. I can
replicate the behaviour by restarting bind (flushing caches I assume).
I thought that one or more of the NS involved was a CNAME instead of an
A record, but I could't find one. So what am I missing here?
This is my bind:
BIND 9.11.3-1ubuntu1.12-Ubuntu (Extended Support Version) <id:a375815>
This is a trace for 172.82.233.25:
$ dig +trace @127.0.0.1 -x 172.82.233.25
; <<>> DiG 9.11.3-1ubuntu1.12-Ubuntu <<>> +trace @127.0.0.1 -x
172.82.233.25
