[AusNOG] My Predictions for the ISP Industry

[Smith, Mark]

Variable length addresses have been done before (TCPv1 (TCP/IP before TCP and IP were split), CLNS), and the majority of humans tend to simple fixed length addressing, even when they have a choice. My understanding is that address lookups would also be harder or at least the hardware to make them fast would also be more expensive.

(TCPv1 supported variable length addresses composed of a number of 4 bit components, with the number of components also encoded as 4 bits, ranging in value from 1 to 15, giving a maximum variable length address size of 60 bits.)

Anyone remember the suggestion to make v6 addresses be variable length strings?

Route my packet to com.facebook.www please.

Or route my packet to org.dotat.atdot at newton where org.dotat.atdot decides what to do with anything following its own prefix.

Crazy? Maybe. I do note however that both "com.facebook.www" and "org.dotat.atdot" fit in the same space as a v6 address and present a self-encoded CIDR-like address.


Mark.
