Based on the log entries that you shared, it looks like the qname is
"loopback.". Is that correct?

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.
