You can turn off IPv6 on a particular interface with
net.ipv6.conf.eth0.disable_ipv6 = 1
Or totally by putting
install ipv6 /bin/true
in /etc/modprobe.d/50-ipv6.conf
You may have to do that if parts of your network aren't ready for it yet.

Subject: [LINUX-390] DNS Question
Hi all,
I am working on a DNS on SLES 11 SP3 using BIND.
I got the DNS working where I can ping my entries etc. But I am getting the
following errors which looks like IPv6.
172.16.1.182 is my local laptop DHCP address. Any suggestions?
