[ppml] Suggestion for ARIN to deligate smaller IP blocks

[John Paul Morrison]

Funny, there never used to be any reason to keep tech savvy small 
businesses from designing and operating their networks properly (ie. 
using BGP instead of NAT hacks or proprietary hardware), and not having 
to renumber.

These are just the same sky is falling arguments that whether 
intentionally or not, have created second class, second tier internet 
users. You're not big enough to justify a /22? Then the attitude is "so 
what" or "get lost" - you have to stay with that bad contract, or use a 
proprietary or ugly NAT hack to stay in business, or you have to renumber. 

This isn't 1995 any more. We're not running out of IP addresses - every 
IPv4 /24 allocated is really just one more step to IPv6.  Routers are 
NOT crashing or having to be upgraded because the Internet routing 
tables are doubling every month.  The Internet saw unprecedented growth 
in the beginning of the Web age because it was new, and we're never 
going to see the same rate of growth.  What we have here is the same old 
arguments: address depletion and routing table size to create a two tier 
internet used as a big stick to keep the little guy in his place. We 
have IPv6 for address space growth, and the IETF saying there's no need 
for panic on the routing table problem (on top of it we have Moore's law 
on our side and the fact that the Internet isn't growing at the same rate).

BTW, I can *already* get provider aggregatable /24 addresses today if I 
can justify them, and advertise these with BGP with another carrier. So 
the next logical step is to have provider independent addresses so I can 
cut the cord with the upstream ISP if their terms are onerous
