The name*server* can nothing do about what the=20 *client* asks of them. The fact that you connect to a nameserver via=20 IPv4 says nothing about what kind of queries you want to send to it. At=20 the moment you can't change the behavior of the resolver in libc and (as=20 far as I know) that of the isc implementation either. There has been a=20 discussion to provide a environment variable to emit only IPv4 queries,=20 though. =2D-=20 /"\ Best regards, | mlaier@freebsd.org \ / Max Laier | ICQ #67774661 X http://pf4freebsd.love2party.net/ | mlaier@EFnet / \ ASCII Ribbon Campaign | Against HTML Mail and News --nextPart5312504.Mh0Yq2qTPc Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.4 (FreeBSD) iD8DBQBG6F6bXyyEoT62BG0RAl8gAJ9Y3lohPtaiP/i259nRLBsXAnnqpQCcC6eD P1IC7lLq4/ws558afifH1l0= =Yjew -----END PGP SIGNATURE----- --nextPart5312504.Mh0Yq2qTPc--
