The earliest copy of the hosts file I could find was

;local stuff

; DoD Internet Host Table
;  22-Mar-85
;  Version number 436

Does anybody have an earlier copy?


This was in the first page of Google search results for "DoD Internet Host Table"; I bet with a little more research I could come up with something much older.  Or one of the PDP-10 folks will find the original...


Perhaps a more interesting question, and one which I cannot quickly answer (nor am I going to go pinging huge swaths of the public internet), is are there any hosts in any version of HOSTS.TXT that are still on the public internet in the same location?  Or - and perhaps there is an easy answer to this that I do not know - is there a repository of old WHOIS databases?  I remember being stymied ~20 years ago that Ultrix had SRI-NIC.ARPA hardcoded in the whois binary and I couldn't find a hostname of the correct length with which to replace it...
