I raised this question in the debian-ipv6 list. Here is the thread:- http://lists.debian.org/debian-ipv6/2007/12/msg1.html Got one solution of installing my own bind9 named which works.

Please help me to disable ipv6 completely. We recently ran into a similar problem. IPv6 has long been successfully black-listed but for a few days we were unable to use Etch to download a Debian Testing CD from the torrent because btdownloadcurses saw the bttracker.acc.umu.se record and died on something like no route to host without ever trying the A record. bttracker.acc.umu.se now (seems to) always return the A record before the record and btdownloadcurses works once more. FWIW, we do not have options ipv6 in resolv.conf, but I don't see a way to say something like options no-ipv6. --Mike Bird -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

How to disable ipv6 in Lenny to avoid 1.0.0.0 error in name resolution for AAAA type queries
I am using Debian Lenny. $ uname -a Linux mylappy 2.6.18-4-486 #1 Wed May 9 22:23:40 UTC 2007 i686 GNU/Linux I changed the alias net-pf-10 ipv6 line to the following two lines. alias net-pf-10 off alias ipv6 off After rebooting, I checked: lsmod | grep ipv6. Sure enough it is gone and the command gives nil output. But when I use bitchx or pidgin to connect to irc.freenode.net, I can still see DNS irc.freenode.net type of queries.As a result our DNS server that doesn't understand ipv6 returns 1.0.0.0 as the address and the clients don't work. First I tried making these changes /etc/modprobe.d/aliases - Result: problem persists (Yes, I did reboot after the changes) Next, I tried adding the two alias off lines in /etc/modeprobe.d/00local - Result: problem persists. Finally, I added the line blacklist ipv6 towards the top (5th line) of /etc/modeprobe.d/blacklist - Result: still the problem persists. I have succeeded to make Iceweasel work by setting network.dns.disableIPv6=true in about:config. But I need a OS-wide solution so that all my network apps do not send ipv6 DNS type requests and they work successfully. Please help me to disable ipv6 completely. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]
