Open Computing History Project

We have finished transcribing a set of ARPANET host tables covering the decade from 1973 to the NCP-to-TCP/IP transition in January 1983. The tables were printed out at regular intervals by a site that kept them for reference, and they were donated to the project last spring along with a box of RFC printouts.

Each table lists host names, addresses and the type of machine at each site, so taken together they show the network growing from a few dozen hosts to several hundred. We have published the transcriptions as plain text alongside page scans, and we have also compiled a single spreadsheet that tracks each host across the years.

A few of the earlier pages were hard to read and some entries are marked as uncertain. Corrections are welcome. If you worked at one of the listed sites and remember what was actually behind a particular host name, we would like to hear from you.
