<DIV><FONT size=2 face=Arial>In this article Geoff posits the possibility of
moving content inside walled gardens using Content Distribution Networks and
extensive use of ALGs as IPv4 conservation methods.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>He considers this in the context that CGNs
may not provide enough address space leverage to facilitate a 10 year
transition to IPv6.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Leaving aside the idea of brokenness brought about

<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>I guess I am asking how many ports the average user
(not server) wants to keep open and available, or whether there are processing
or logging limits which serve to restrict that multiplier? Are there other
scaling limits? Trends towards higher per-user port use? </FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>My impression is that a 10:1 ratio is quite
feasible, (assuming you want to punish your customers with degraded service,
yada yada).</FONT></DIV>

<DIV><FONT size=2 face=Arial>I found it a very worthwhile article to read, and
think it conveys valuable information to those interested in ARIN policy
development.</FONT></DIV></FONT></DIV>
