<br>If there are no more IPv4 addresses to be allocated by the RIRs, the routing tably still will increase due to exchangeng (selling) slots of addresses.<br><br>OK. if we would be able to stop the increase of the IPv4 address entries at 440 000 then we would have rooms for 30 000 IPv6 routing entries.<br>
<br>30 000 IPv6 entries are not too many, there are more AS in use today.<br><br>Therefore it would be better to stop the increase at lower level - otherwise huge investment will be needed world wide soon.<br><br>In the other hand if the small IP address slots would be very limited both at IPv4 and IPv6 level then the IPv4->IPv6 transition could be executed with the line cards capable to handle 0.5M IPv4 routes.<br>
<br>Either we restrict ourself within a narrow lane or hugh investments AND toleration of SLOW DOWN is unavoidable.<br><br>Best,<br><br>Géza <br><br><br><br><br><br><br><br><br><br> <br></div><blockquote class="gmail_quote" style="margin:0pt 0pt 0pt 0.8ex;border-left:1px solid rgb(204, 204, 204);padding-left:1ex">
