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:
Based on the log entries that you shared, it looks like the qname is "loopback.". Is that correct?
$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
I would expect that you could define a new zone ~> tld that is "loopback", just like — what appears to be — the localhost. zone above.
You won't be able to use a CNAME from loopback. to localhost. b/c of problems with CNAMEs in the apex. I don't know if a dname would work or not. Though I don't think that you need a cname or dname. Read: I think a new "loopback." zone (like the "localhost." zone above) would suffice for your needs.
This really sounds to me like any generic new / custom (read: squatting) TLD.
