turning off ipv6 in Suse 7.2

hi list, i would like to know how to disable ipv6 on my networkcard on SuSE Linux 7.2 which is activated by default. I got a tip that changing alias net-pf-10 off in the /etc/modules.conf instead of: alias net-pf-10 ipv6 would help, but there is no such entry...maybe anyone could help?
