[arin-ppml] Draft Policy ARIN-2017-5: Equalization of Assignment Registration requirements between IPv4 and IPv6

[Roberts, Orin]

“Since we require SWIP for IPv4 /24s”

ARIN also currently requires a SWIP for an IPv4 /29 , which makes  “/60" a more applicable reference point; unless the intent is to minimize or eliminate SWIPs for IPv6 (ISPs won’t mind).

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.

Regards,
Bill Herrin
