[ih] Protocol numbers (was IP version 7)

[vinton cerf]

I left ARPA around October 1982 to join MCI and build MCI Mail. BBN
supplied the network.
I left MCI (the first time) in June 1986 to join Bob Kahn at CNRI. Since I
remember the MATNET, I suspect it might have gotten its start in the early
1980s while SATNET was still running. Jack H, do you know?
I left CNRI in October 1994 to join MCI a second time, staying until
October 2005 at which point I joined Google.
