Well, you can safely ignore this! I realized afterwards that '--disable-ipv6' just disables the default use of IPv6 in BIND, it doesn't completely disable the protocol. Turns out I was querying the wrong address with DIG when testing this, too. listen-on-v6 certainly works as expected, and enables IPv6 like it should. Although, that still does beg the question, why don't we want IPv6 enabled by default on new BIND installations? - Mark -- Mark Kamichoff prox@prolixium.com http://www.prolixium.com/ [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) iEYEARECAAYFAkyWXKAACgkQ0TYC9KtF8BPJKgCeMyQA2FLrz3t7TqzNXc7bt/GQ xAcAnj3XEXwppM1+JFnWuSd6nmdtyUHi =4roe -----END PGP SIGNATURE-----
