jumping in late :) with less than I'd like of v6 experience :) I think the
debate goes something like: "use /64 cause autoconf works!" (and it's in
the spec as 'lan' links get /64's) and the other half is your debate of 18
million billion addrs for a ptp sonet link is craziness (and wasteful) and
/126's work fine since we never autoconf things we are going to ping
monitor.
