I believe this problem statement is incorrect, and therefore oppose the
policy proposal as-is.
8.5.4 was intended (by me, as one of the authors, and in PPML discussions I
just pulled up) to allow ISPs to transfer a /24 without justification. It
was *not* intended to "match the previous policy" in 4.2.2.
8.5.5 reads "8.5.5. Block size
Organizations may qualify for the transfer of a larger initial block, or an
additional block, by providing documentation to ARIN which details the use
of at least 50% of the requested IPv4 block size within 24 months. An
officer of the organization shall attest to the documentation provided to
The intention was that any ISP needing a /21 would need to "provide
documentation to ARIN which details the use of at least 50% of the
requested IPv4 block size within 24 months", with officer attestation to
If that policy is deemed insufficient, and we believe it's better to allow
transfers of up to /21 without providing documentation to ARIN and officer
attestation of such, then this proposal would need to be re-written with a
new problem statement justifying that.
