At least if ever we do run out of IP's we can re-number all our point to point links and get a crapload of address space back :) ... <br><br><div class="gmail_quote">On Wed, Apr 6, 2011 at 5:42 PM, David Hughes <span dir="ltr"><<a href="mailto:David@hughes.com.au" target="_blank">David@hughes.com.au</a>></span> wrote:<br>

Hate to show my age here but years ago (1993 perhaps) I spoke at the Internet Society's conference in San Francisco. I remember watching a presentation by Peter Ford when he was getting the gospel according to CIDR out into the public. The 2 points below sound very similar to the reasons we needed to roll out CIDR. What's wrong with giving everyone who needs more than 3 * /24's a /16 I ask you?<br>
<br>
So to answer Graham's original question : why allocate 8,446,744,073,709,551,616 addressed to a point to point link? Because our industry has a bloody bad memory.<br>
