Now, some may take that as a sign the IETF needs to figure out how to handle 10^6 BGP prefixes... I'm not sure we'll be there for a few years with IPv6, but sooner or later we will, and someone needs to figure out what the Internet is going to look like at that point.
It won't look good. ISPs will have to buy much more expensive routers. At some point, people will start to filter out routes that they feel they can live without and universal reachability will be a thing of the past.
But don't we filter out routes we feel we can live without *right now* without the world ending? I mean, who accepts prefixes longer than /24 these days anyway? We've all decided that we "can live without" any network smaller than 254 hosts and it hasn't made a lick of difference to universal reachability. What's to stop someone who wants to carry around less prefixes from saying, "Bugg'rit, I'm not going to accept anything smaller than a /18"? - mark -- Mark Newton Email: newton@internode.com.au (W) Network Engineer Email: newton@atdot.dotat.org (H) Internode Systems Pty Ltd Desk: +61-8-82282999 "Network Man" - Anagram of "Mark Newton" Mobile: +61-416-202-223
