[ih] IP versions 1-3

[Vint Cerf]

NCP is totally separate

Versions 1-2 of tcp were followed by versions 3 and 4 in which IP was split
out

There was no IP version 1-2 except that routers (gateways) knew about TCP
headers in versions 1-2 of TCP and with version 3 they only knew about IP
headers.

Subject: [ih] IP versions 1-3

I tried to such through the archive, but I haven't found any discussion on
what happened to IP versions 1-3. Do there exist protocols or proposals for
IP protocols prior to what became v4, or what was the reason for naming it
IPv4? Is e.g. NCP regarded as one of those pre v4 versions?
