[arin-ppml] Proposal - Remove Initial Small Assignment Requirements for IPv6

[hostmaster at uneedus.com]

I was still in high school, and ARPA only ran at the university, so I 
guess I missed this part.  I got to play with it mostly after the 
1/1/1983? date.

So running 2 protocols has already been done once already?  I guess the 
only thing we missed with this IPv4/IPv6 dual stack bit is we failed to 
set a drop dead date.

Too bad we did not, or this problem would not exist.

Because that was a hot cut, that would have been the perfect time to do this, but of course this would have increased the work load to do so, since every piece of network software assumed 32 bits at this time and would have had to be updated and recompiled.  At this time, the number of nodes was under 1k and a billion addresses seemed like it would never run out.  If we slid that to say 64 bits at that time, I doubt that IPv6 (IPng) project would have ever been started.  But it did not, and we still are stuck with a 32 bit IPv4 address.
