Googling "Mandriva disable IPv6" the very first result returned yielded this:

"Slow or unreliable DNS lookups because of IPv6 support

If DNS lookups often fail or report answers after a very long timeout only, the IPv6 support may be causing trouble. Under some circumstances, DNS resolvers take a long time to lookup the address using the IPv6 protocol, even if all interfaces use IPv4 only.

IPv6 support in enabled by default in Mandriva Linux 2006. To disable IPv6, add NETWORKING_IPV6=no in =/etc/sysconfig/network=, and reboot your computer so that all IPv6 modules get properly unloaded. "
