Hi Philip, Thanks very much for your comments. I will respond fully as soon as I can - hopefully in the next few days.
The question of how many end-users could be served from a single Mapped Address Block (a single BGP advertised prefix, which is managed by Ivip) is important, but depends on many assumptions. Broadly speaking, MABs could be quite large, such as /12 or /16 and many end users would be happy with one, or four, or 16 or sometimes 256 IP addresses. Hosting companies and some other end-users with lots of servers, or desktop machines they didn't want to put behind NAT, would need more space, of course. The end-users served by a map-encap scheme will include large numbers of end-users whose address space requirements are quite modest - tiny by comparison with the space used by current PI end-users with ASNs. This will be particularly the case with mobility, where most end-users would probably be happy with a single IPv4 address. So there could be 64k happy end-users in a single /16 MAB. As long as the figure averages 5 or 10 or more end-users per MAB, I think we should consider this worthwhile progress. - Robin -- to unsubscribe send a message to [EMAIL PROTECTED] with the word 'unsubscribe' in a single line as the message text body. archive: <http://psg.com/lists/rrg/> & ftp://psg.com/pub/lists/rrg
