Some devices will refuse to work if you subnet smaller than a /64. (Yes, poorly designed, etc.)
Actually, no - not poorly designed. The spec says it must be a /64 (excluding those starting with 000 binary) so that is what devices (rightfully) expect. Ref: http://tools.ietf.org/html/rfc4291#section-2.5.1
I was just trying to head off the flood of "poorly designed" comments last time I said such a thing on a different list. ;) I find /64 convenient because it ends on a nice boundary out of my /48 and for my purposes it's more than enough space. The only annoyance I've come across was my Cisco devices will only accept an EUI-64 address as a host address in an ACL. Not a big deal though. ~Seth
