Re: v6 subnet size for DSL & leased line customers

Once upon a time, Owen DeLong <owen@delong.com> said:

I think it makes sense to assign as follows:

/64 for the average current home user. /56 for any home user that wants more than one subnet /48 for any home user that can show need.

Dumb question alert: why the 8 bit boundary? That makes sense for IPv4, where reverse DNS delegation is cumbersome on non-octet boundaries, but IPv6 reverse DNS can be delegated at the nibble boundary. Why not assign /60, /52, etc.? A /60 would probably satisfy virtually all home users (up to 16 subnets) for example. -- Chris Adams <cmadams@hiwaay.net> Systems and Network Administrator - HiWAAY Internet Services I don't speak for anybody but myself - that's enough trouble.
