[ppml] Suggestion for ARIN to deligate smaller IP blocks

John, I'm a little confused by your math.

2000 customers * cost of changing IP addresses equals... $200 per  
customer if they have to pay an outside consultant to do it for them,  
usually less than $20 for inside help... Not a big number.
$40,000 <=> $400,000

Cost of upgrading a single big iron box to have more routing table  
slots > $100,000
Multiply by the number of big iron boxes who can't use a default  
route, say at least 400?

The only difference is who is paying for it, and who is gaining value  
for it.  You want us to pay, so that your business can gain value.

You do the math, and tell me again why I should be paying out of my  
pocket for your customer.  You very well could have explicit  
instructions sent to the customers for IP address changes.  You could  
very well purchase multiple IP ranges from different providers, and  
thus make the importance of any IP address change negliable.  Or you  
could pay $49/month to get a second uplink and then qualify for PI  
space based on multi-homing.

Every one of those options is trivially cheap and easy to implement.   
This is why I reject your desire to make our businesses pay hard cash  
so that your business can avoid building even the most trivial  
resiliance into your process.
