Draft Policy ARIN-2012-7
Reassignments for Third Party Internet Access (TPIA) over Cable

Date: 12 October 2012

Policy statement:

Insert new section to NRPM to read as follows: IP addresses reassigned by an ISP to an incumbent cable operator for use with Third Party Internet Access (TPIA) will be counted as fully used once they are assigned to equipment by the underlying cable carrier provided they meet the following requirements:

* initial assignments to each piece of hardware represent the smallest subnet reasonably required to deploy service to the customer base served by the hardware

* additional assignments to each piece of hardware are made only when all previous assignments to that specific piece of hardware are at least 80% used and represent a three month supply

* IP allocations issued through are non-transferable via section 8.3 and section 8.4 for a period of 36 months. In the case of a section 8.2 transfer the IP assignment must be utilized for the same purpose or needs based justification at a rate consistent with intended use.

A unique situation exists particularly, and perhaps only, in the Canadian region that is preventing legitimate ISPs from obtaining subsequent allocations of IPv4 addresses for use with the Third Party Internet Access
(TPIA) framework that has been mandated by the CRTC (Canada's version of the FCC). Adding this section to the NRPM will allow ISPs that intend to make use of this CRTC mandated framework to obtain the number resources that they require but are currently unable to obtain.

Timetable for implementation: immediate
