If using dig you can either do:
dig -x 127.0.0.1
OR
dig 1.0.0.127.in-addr.arpa PTR
That is going to query the primary name server listed in /etc/resolv.conf
- so unless it has a reverse zone setup for the l27.x block you will not
get an answer back or you will get an answer like the one you have below.
Same data on for both commands on both servers...
biz-net2# dig -x 127.0.0.1 | egrep '^[a-z0-9]'
1.0.0.127.in-addr.arpa. 604800 IN PTR localhost.
127.in-addr.arpa. 604800 IN NS localhost.
localhost. 604800 IN A 127.0.0.1
localhost. 604800 IN AAAA ::1
biz-net2# dig 1.0.0.127.in-addr.arpa PTR | egrep '^[a-z0-9]'
1.0.0.127.in-addr.arpa. 604800 IN PTR localhost.
127.in-addr.arpa. 604800 IN NS localhost.
localhost. 604800 IN A 127.0.0.1
localhost. 604800 IN AAAA ::1
What¹s the actual problem you are trying to solve though?
Problem is ParaDNS is failing on all lookups for this server.
