This is a good rewrite of this, and you can count me in favor.

>       Current ARIN policy has different WHOIS directory registration requirements for IPv4 vs IPv6 address assignments.
>       IPv4 registration is triggered for an assignment of any address block equal to or greater than a /29 (i.e., eight IPv4 addresses).
>       In the case of IPv6, registration occurs for an assignment of any block equal to or greater than a /64, which constitutes one entire IPv6 subnet and is the minimum block size for an allocation.
>       Accordingly, there is a significant disparity between IPv4 and IPv6 WHOIS registration thresholds in the case of assignments, resulting in more work in the case of IPv6 than is the case for IPv4.
>       There is no technical or policy rationale for the disparity, which could serve as a deterrent to more rapid IPv6 adoption.
>       The purpose of this proposal is to eliminate the disparity and corresponding adverse consequences.

>         Currently, assignments of /29 or more of IPv4 space (8 addresses) require registration
>         The greatest majority of ISP customers who have assignments of IPv4 space are of a single IPv4 address which do not trigger any ARIN registration requirement when using IPv4.
>         This is NOT true when these same exact customers use IPv6, as assignments of /64 or more of IPv6 space require registration.
>         Beginning with RFC 3177, it has been standard practice to assign a minimum assignment of /64 to every customer end user site, and less is never used.
>         This means that ALL IPv6 assignments, including those customers that only use a single IPv4 address must be registered with ARIN if they are given the minimum assignment of /64 of IPv6 space.
>         This additional effort may prevent ISP's from giving IPv6 addresses because of the additional expense of registering those addresses with ARIN, which is not required for IPv4.
>         The administrative burden of 100% customer registration of IPv6 customers is unreasonable, when such is not required for those customers receiving only IPv4 connections.
