<pre>Hello,
FYI, every other RIR allows partial block sales down to the minimum transfer size.
This might mean a negative impact due to route de-aggregation, but it has a positive impact on the supply of addresses for the market, as address-holders can sell small sections of their holdings that might be unused, without the need for emptying the entire block.</pre>

I think some text to cap the minimum transfer size to a /24 is still
reasonable from a router FIB resource management perspective. I know
it's not the RIR's job to be "operational", but given that IPv4's
last legs could easily cost Internet infrastructure dearly, I think
it's prudent.</div><div style="background-color:rgb(255,255,255);color:rgb(0,0,0);font-family:Tahoma;font-size:16px" text="#000000" bgcolor="#FFFFFF"><br>
