Hello,

I run a root server mirror like described in https://tools.ietf.org/html/rfc7706#appendix-B.2
on a ipv6 only host. Not sure if the behavior is new but just noticed it:

Initial I start without a local "zonefile", without a database ( nsd.conf has database: "" )
and also removed xfrdfile.
I expect nsd /immediately/ start fetching the zone from a master. But sometimes it take 2 minutes:

The next time I start with "empty" nsd, it try via ipv6 first and operate as expected.

Is there any preference or a missing selection on the protocol used for zone transfer?
