I’m looking for some direction/reading list of how to properly configure IPv6. I’ve read to use a /64 for PtP interfaces and I’ve read use a /128 instead. Assign all loopbacks from the same /64, use a different /64 for each loopback. Ect, ect.
Hi Matthew, Suggest /128's for loopbacks and /124's for point to points, all from the same /64. This way you don't burn space needlessly, don't open yourself to neighbor discovery issues on point to points and can filter inbound Internet packets to that /64 in one fell swoop so that it's harder to hit your routers directly. Just make sure not to filter the outbound packets. Reminder: No matter what size you pick, use nibble boundaries for visual and DNS convenience. So /124, not /126.
