Quite the opposite in fact. In IPv6 a /64 is roughly equivalent to a /32 in IPv4. As in, it's the smallest possible assignment that will allow an end-user host to >function under normal circumstances.
SWIP or rwhois for a /64 seems excessive to me, FWIW.
IPv4/32 is both a routing endpoint and a host. IPv4 is a 32 bit combined routing and host space. IPv6/64 is a routing endpoint and v6/128 is a host. IPv6 is a 64 bit routing space and also a 64 bit host space for each routing space, not a 128 bit combined routing and host space. Evidently, the whois requirement is for networks, not nodes, which makes sense when you think about how the entity that controls a /64 is assuming responsibility for 2^64 network nodes. -----Original Message----- From: Doug Barton [mailto:dougb@dougbarton.us] Sent: Monday, December 10, 2012 5:05 PM To: Schiller, Heather A Cc: Constantine A.

I think most folks would agree that, IPv4 /32 :: IPv6 /128 as IPv4 /29 :: IPv6 /64
