Hello all, I have a small problem, and I was wondering if someone could help
me. My bind9 dns gets a query for loopback. I have tried and tried to define
the word loopback in the dns as a forward zone with reverse loopkup, but
doesn't seem to take. I have tried to CNAME it using localhost, but that
doesn't seem to fix it either. My version of BIND is: BIND 9.12.3 <id:6c8e92c>
Can someone please help? Please help me define loopback so that request for
loopback does not fail as in the entries below. My localhost configurations are:
$TTL 3h
$ORIGIN localhost.
@ 1h IN SOA @ root (
02112008 ; serial
3600 ; refresh 1 hour
2H ; retry 1 half hour
4W ; expiry after 2 weeks
1h ; minimum TTL
)
@ IN NS @
IN A 127.0.0.1
TTL 3h
@ IN SOA localhost. root.localhost. (
02112008 ; Serial
3600 ; Refresh after 1 Hour
1800 ; Retry after 1 Half Hour
1209600 ; Expire after 2 Weeks
86400 ) ; Minimum TTL 1 Day
IN NS localhost.
1 IN PTR localhost.
