Subject: Accept dns proposals for the loopback addresses
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=665c92da575e4726f1b8c5398ee77a224336ae54;p=openbsd

Accept dns proposals for the loopback addresses

Don't reserve^Wignore them for unwind(8);  there are non-unwind use-cases
and so far resolvd(8) always seems to do the right thing when proposing
localhost while unwind is running.

OK benno
