[ih] Fw: Nit-picking an origin story

[Vint Cerf]

the fake host was a software construct in the IMPs that looked like 1822
hosts to the IMP internal software. There were four fake hosts as I recall.
I used them to generate traffic, to receive traffic, to trace specially
marked packets that flowed through the network (at least, I think I
remember that is how the traces were captured and sent to a destination for
logging)...you could attach a terminal to the imp and use a fake host
through which you could interact with a server at the other end - probably
that is how the so-called Terminal IMP (TIP) was built but for many
terminals, not just one.
