none of which seem to move us forward. i guess the lesson is that, as long as we are well below moore, we just keep going down the slippery, and damned expensive, slope.

As long as we keep using IPv4, we are mostly stopping at /24 and must stop at /32. But, see the subject. It's well above moore. For high speed (fixed time) routed look up with 1M entries, SRAM is cheap at /24 and is fine at /32 but expensive and power consuming TCAM is required at /48. That's one reason why we should stay away from IPv6. Masataka Ohta
