Can't help on the main thrust of this, but can answer one question...

NIC is probably what became know as SRI-NIC in latter days. By the time I
joined the internet in the early 80s, SRI-NIC was where you registered your
domain name. I just missed the hostfile by a few years.

It's TENEX or TOPS-20 (they are the same for this purpose). <DIR>FILE.EXT
was the format. This was later extended to <DIR.SUB>FILE.EXT. So the <>
just contain the whole path, separated by dots.
