Maybe $400,000 is noise to your company.  My company has to think
long and hard before spending $40,000.  Your perspective is seriously
warped.

Are you talking about the cost of upgrading all the backbone routers
in the world to handle /25's vs. /22's?  (I forget the size Leroy 
was originally looking for, but it was about 1/8 the minimum 
assignment under the current rules.)

Aren't all these big boxes going to need to be upgraded anyway to
support IPv6?

Who is "us"?

Don't you need to be able to justify a /22 to get the PI multihoming
space?  That was the basis of this whole discussion.

Why does it cost your business any more if Leroy has a /25 that he
is using most of versus if he has a /22 that he doesn't really need?

Are you on about routing table size again, or something else?
