I believe this policy, as written, is misleadingly titled. I support the
intent expressed in the title, and support either the "more than a /60"
language or (preferentially) Bill's "more than a /56" language below for
equalizing assignment registration requirements between IPv4 and IPv6.
However, I definitely do not support also relaxing the "/29 or more"
requirement for IPv4 without a significant revision of the problem
statement to indicate why such a change is justified, and a retitling of
the proposal. And even with those changes, I likely would not support
relaxing the "/29 or more" requirement. For context, my employer currently
has a large number of /29 networks reassigned from our upstream transit
providers (one for each link for unique routing purposes). Those currently
are not reassigned to us in whois (in contravention of ARIN policy), but it
would be better for us (for geolocation purposes, for example) if they were
