Hi Leif,

IMHO, IPv6 /48 = IPv4 /24. Since we require SWIP for IPv4 /24s, we should
require it for IPv6 /48s.

I'd be comfortable with "more than a /56" and "more than a /60." I prefer
"more than a /56."

I would oppose "/60 or more" or "/56 or more" because I believe that would
encourage ISPs to engage in unhealthy assignment practices to avoid SWIP
reporting, such as assigning /64s, /61s and /57s.
