[arin-ppml] ULA-C and reverse DNS

Corrected fragment below. As some may have guessed, I really
meant to say /23.

------------------
Am I confused here? Didn't our experiences with the swamp 
give us VLSM and CIDR? These are good things. As is the whole 
ARIN policy process which also was driven by experiences in 
the swamp. I remember when I could ask for a /23 allocation, 
and get two adjacent but non-aggregatable swamp /24 blocks instead.
That was due to lack of process, and lack of oversight. The 
swamp was a good thing. It also drove vendors to better 
algorithms in the routers (Patricia tries?) and better 
hardware (TCAMs).
