Those serving areas then have smaller DHCP pools (generally /27’s or /28’s) assigned at the node level. End-users are assigned IP’s from the DHCP of the node they are served by. Once the space is provided to the TPIA provider the ISP no longer has control over the routing, renumbering or specific assignments within the TPIA network.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'> <o:p></o:p></span></p><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0cm 0cm 0cm'><p class=MsoNormal><b><span lang=EN-US style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>From:</span></b><span lang=EN-US style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> arin-ppml-bounces@arin.net [mailto:arin-ppml-bounces@arin.net] <b>On Behalf Of </b>Scott Leibrand<br><b>Sent:</b> July-27-12 3:46 PM<br><b>To:</b> Bill Sandiford<br><b>Cc:</b> arin-ppml@arin.net<br><b>Subject:</b> Re: [arin-ppml] New Policy Proposal<o:p></o:p></span></p></div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Can you explain the process of how IP addresses are assigned, reassigned, and used for TPIA?

Proposal Version: 1<br>4. Date: July 27, 2012<br>5. Proposal type: new<br>6. Policy term: permanent<br>7. Policy statement:<br>Insert new section to NRPM to read as follows:<br><br>4.2.3.8 Reassignments for Third Party Internet Access (TPIA) over Cable<br><br>When IP address resources are reassigned by an ISP to an underlying cable<br>carrier for use with TPIA, those addresses shall be deemed as utilized<br>once they are assigned to equipment by the underlying cable carrier.<br><br>8. Rationale:<br>A unique situation exists particularly, and perhaps only, in the Canadian<br>region that is preventing legitimate ISPs from obtaining subsequent<br>allocations of IPv4 addresses for use with the Third Party Internet Access<br>(TPIA) framework that has been mandated by the CRTC (Canada's version of<br>the FCC). Adding this section to the NRPM will allow ISPs that intend to<br>make use of this CRTC mandated framework to obtain the number resources<br>that they require but are currently unable to obtain.<br>9.
