[arin-discuss] use of 128.66.0.0/16 not clear

[Owen DeLong]

I think that now is NOT the time to be expanding the wasted IPv4
address space.  This block should be documented for it's prior
misuse in examples.  That use should be deprecated, and, the block
should be placed in the free pool.

I would not object to placing it low on the priority list of blocks to  
be
issued, but, that's 65,536 IPs that should not be left fallow simply
due to prior misuse.
