Oh, and before anyone jumps all over me, I am NOT implying you should deaggregate and blow up the table. Just that 300K prefixes is the DFZ is not a reason to start filtering /24s. Today. :)
given o ipv4 bits not scaling to internet growth o increase in multi-homing o internet growth nats, siit/nat-pt and ipv4/ipv4 nat will increasecombined, this very well may create pressure to globally route longer ipv4 prefixes.
