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.

I found this bit of research from 2007 (
http://www.cise.ufl.edu/~wlu/papers/tcam.pdf ).  It seems to me there
are probably more ways to mix and match different types of ram to be
able to deal with this beast.
