I just received an email via the arin-ppml (public policy mailing list) announcing a new version of the ARIN Number Resource Policy Manual (NRPM); NRPM 2010.2.  This particular version is significant to me in that it implements a policy that I co-authored: 2008-7: Identify Invalid WHOIS POC’s.

The ARIN announcement lays out all the relevant details quite succinctly, so I have included it here, rather than re-stating it all myself:

On 1 July 2009 the ARIN Board of Trustees, based on the recommendation
of the Advisory Council and noting that the Policy Development Process
had been followed, adopted the following number resource policy:

2008-7: Identify Invalid WHOIS POC’s

A new version of the ARIN Number Resource Policy Manual (NRPM) has been
published to the ARIN website. NRPM version 2010.2 contains the
implementation of 2008-7. The new policy text can be found in the NRPM
in Section 3.6 Annual WHOIS POC Validation. For more information on POC
validation, please see:
