you can.  there was a bit of a war in the ietf some years back, and yhe
64 bit boundary is a convention.  hardware must route and forward on 128
bits.

do other than 64 and you do not get auto-conf.  some do not consider
this a loss, others do.

i wonder what strange gear you tried.  all routers, cisco and other, i
play with operate on 128 bits.
