Hello, I'm looking for old DNS software - servers, clients, libraries. The oldest one I've found is BIND 4.3 from 4.3BSD (and it works as a resolver on 2019 Internet), but there were earlier ones - http://www.donelan.com/dnstimeline.html says that UCB released first BIND in 1985, something was running on earlier servers. Any help would be appreciated. Witold Krecicki
