Umm, hard to remember that long ago, and haven't looked at IENs in ages, but should memory serve me correctly, the first TCP/IP documents I read were circa 1978, and the cutover was circa 1983.
I was a system/network admin at the University of Texas at Austin when the old ARPNET NCP was phased out in favor of IPV4. There was not a single cutover date, but rather both protocols were run side by side for a few years as I recall. This allowed plenty of time for testing, etc. Of course, the installed system base was much smaller in those days. UT had 3 machines directly connected to the local ARPANET IMP and no campus area network. In 1983 the 128.83.0.0/16 assigned to UT was just being deployed. So the cutover to IPV4 was relatively easy. A major change in the operational protocols today would have a much greater impact and require a much longer deployment and testing cycle. -- Smoot Carl-Mitchell Systems/Networking Consultant email: smoot () tic com cell: +1 602 421 9005 home: +1 480 922 7313
