Policy Proposal Name: Rationalize Multi-Homing Definition and Requirement

Author: Robert Seastrom

Policy term: permanent

Policy statement: In existing policy, replace the phrase
      "multi-homed organizations must:" with the phrase "organizations
      applying under the multi-homed policy must:"  In existing policy, replace "Provide information showing that the requested
      IP address space will be utilized within three months." with
      "Provide information showing that the requested IP address space
      will be utilized within three months and demonstrating an intent to
      announce the requested space in a multi-homed fasion."

Rationale: Presently, organizations wishing to apply for their first
      address space under the multi-homed policy must demonstrate that
      they have ALREADY announced a DIFFERENT address block via
      multi-homing, while simultaneously promising to renumber out of
      that same block. This creates needless make-work for ISPs which are
      planning to multi-home, related to old resources which they're
      already trying to get out of.  Likewise, it creates needless work
      for both of their upstream providers, who have to temporarily
      announce a prefix which DOESN'T NEED to be multi-homed, solely to
      demonstrate to ARIN analysts that the applying ISP is multi-homed.
      However, this same criterion can be demonstrated just as
      effectively by the applying ISP showing the analyst contracts with
      multiple ISPs under which the newly-applied-for block WILL BE
      multi-homed, and this more accurately reflects the intent of the
      original policy, while removing needless make-work at a time when
      the applicant is surely already quite busy with the real
      requirements of their change-over.

Timetable for implementation: immediate
