Regurgitating the original e-mail for context and follow-up.
General responses (some that didn't make it to the list): - "There really is that much space, don't worry about it." - /48s for those that ask for it is fine, ARIN won't ask unless it's a bigger assignment - /52 (or /56) on smaller assignments for conservation if it makes you feel better - Open question on whether byte/octet-boundary assignment (/56 vs /52) is better for some reason
Octet boundary, not really. Nibble boundary, yes. Both for DNS delegation convenience and for human factors issues.
I haven't seen anything on the general feel for prefix filtering. I've seen discussions from /48 down to /54. Any feel for what the "standard" (widely deployed) IPv6 prefix filter size will be?
So far, mostly it's /48 with a few select providers trying to hold the line at /32. Owen
