hi. i've spare hardware and intend to setup an island of ipv6-ony network using centos5 to test few things and part of effort to understand ipv6.

at the moment the machines boot up having ipv4 (rfc1918) addr and link local (fe80) ipv6 addr. i manually add site local (fec0) ipv6 addr after the machines up. how do i drop the ipv4 and the link local ipv6 addr automatically? anyone has (links of) good docs on how to setup ipv6-only network? tqvm
