It was thus said that the Great Mouse once stated:
And I spend over $80/month for DSL to a provider that gives me a /29
and a /60 from globally routed space. (That everything is now CIDR
blocks is another loss; I am not fond of the desupporting of
noncontiguous subnet masks, even though I can understand it - I'm the
only person I've ever heard of running that way other than for
testing.)
One benefit of contiguous subnet masks is that it makes routing faster.
It's still a linear search, but it's based on the average length of the
netmask instead of the total number of entries. Granted, I'm looking at
this from the perspective of a router and not a computer (which might have a
few routing entries vs. hundreds or thousands). I've implemented such an
algorithm to deal with spam (quick address lookup).
