Hi all,
i was doing some little research, read up the RFC, and thanks to Scott for
doing a good breakdown of the list..
Now, what about 14.0.0.0/8 & 39.0.0.0/8? Has these been returned to the
registries for assignment or are they still reserved?
I know for sure that the 24.0.0.0/8 is already being assigned outhere in the
Internet..
any ideas?
Thanks in advance guys.
Cheers.
-K
