Re: IPv4 smaller than /24 leasing?

[Justin Wilson <lists () mtin net>]

Even to buy it on the secondary market you have to have justification and show usage.  So if someone buys a /24 and 
really only needs a /25 then what? It ARIN, or others for that matter, going to relax those requirements?  If I am an 
ISP and need to do BGP, maybe because I have a big downstream customer, I have to have a /24 to participate in BGP.   I 
see these scenarios more and more.
