I just checked my archives of our TOPS-20 PDP-10 filesystem (retired 31-Oct-1990); the oldests hosts.txt file has a filesystem timestamp of 30-Apr-1986, with 3210 lines, of which 3124 are hostnames (98 of them at the University of Utah). The comment header says ; DoD Internet Host Table ; 28-Apr-86 ; Version number 534 If someone / some site wishes to collect hosts.txt generations for a historical record, let me know offlist, and I'll supply a pointer to a copy of my file. Sadly, it looks like we just replaced PS:HOSTS.TXT with a new generation from time to time, purging previous generations (a legacy of the days when a washing-machine-sized 200MB disk drive and cabinet cost US$15,000). ------------------------------------------------------------------------------- - Nelson H.
