Agreed.

Looking at the BGP tables, I see lots of holes in the address space. A
particularly big one is almost a quarter of IPv4 space -- 65.0.0.0 -
126.255.255.255, which is listed as reserved by ARIN.
Since IPv6 can be seen on the horizon, maybe they should start
allocating some of this, and stop forcing people into problematic
situations like using RFC1918 addresses in the core by artificially
creating scarcity?
And what about 5.0.0.0/8 and 7/8 and 11/8 etc. that are all listed as
allocated but are not used. Due to the scarcity of this public
resource, should there not be some sort of "use it or lose it" policy?
Cheers,
