While I understand that some place may want to put policies that every
v4 part must be exactly same as v6 I think more realistic view is better.
You should have servers ready to answer v6 but look at your traffic -
is it really necessary to add v6 to your load-balancer or would it be
ok to just have AAAA record pointing to particular system (even if 7
others are available) because the amount of traffic makes more sense.
Now when v6 traffic increase there would be more pressure for vendors
to make load-balancers support v6 as well and you'd not have problems
then. But if you're still thinking about v6 load-balancers, then I
recommend taking a look at http://kb.linuxvirtualserver.org/wiki/IPVS
