Re: 20402 routing entries

["Peter S. Ford" <]

Could the RIPE and Merit folks please analyze the current routing 
tables looking for the largest blocks of addresses that could be 
aggregated and determine who they belong to?  

This way we can look for maximum leverage.  

I know you guys don't want to hear this, but it is a good idea to look
for similar leverage via renumbering.  If every provider did a quick 
scan of their customners with  pre-CIDR allocated class Bs and Cs,
figured out how many hosts there are withing each of these network
numbers, and contacted those who have fewer than (let's start low) 10
hosts and got them to renumber, we could get real savings.

How many class Cs are out there to service a slip line going to 
someone's house and a few machines?

We are in the middle of renumbering a couple of K-12 nets like this in
New Mexico, placing them within a CIDR block (thanks to Phil Wood/LANL).  
The work takes a short time (small number of hosts).  Net effect will be
these routes turn into vapor.

Think globally, act locally,
