The language of "b)" actually makes more sense with a /47:
Each static IPv6 assignment containing a /47 or more addresses, or subdelegation of any size that will be individually announced, shall be registered in the WHOIS directory via SWIP or a distributed service which meets the standards set forth in section 3.2.
The major difference is that this language eliminates the SWIP requirement for /48 blocks that are not announced, but all larger blocks require SWIP, and blocks smaller than /48 are also exempt and of course also non-routeable.
This is best for those that think SWIP should be limited to only blocks that are individually announced. I could go either way on this issue.

Shepherd of the draft policy chiming in. Thanks for the lively discussion, everybody. There's certainly a lot to think about here. Just as a reminder to folk, the current policy under question is located here: https://www.arin.net/policy/nrpm.html#six551 And, to help clarify some confusion, per 6.5.5.3.1 (https://www.arin.net/policy/nrpm.html#six5531) residential customers "holding/64 and larger blocks" may use censored data, i.e. "Private Customer/Residence" in lieu of actual names and street addresses. -- With that said, I have a couple of questions to ask, based on potential rewrites that are brewing. First: Assuming a preference for /56 (based on PPML feedback) for the moment, which is the more preferential rewrite of the opening sentence of 6.5.5.1? a) Each static IPv6 assignment containing a /55 or more addresses shall be registered in the WHOIS directory via SWIP or a distributed service which meets the standards set forth in section 3.2. b) Each static IPv6 assignment containing a /55 or more addresses, or subdelegation of any size that will be individually announced, shall be registered in the WHOIS directory via SWIP or a distributed service which meets the standards set forth in section 3.2. Second: Given your specific choice of A or B, are you preferentially inclined to choose the provided bit-boundary, or "/48" Third: If none of these options are palatable, do you have a proposed approach? Thanks, Leif Sawyer Advisory Council
