This is more of an "Internet question" than a "Unix question," since the Internet distributed name service protocol was developed as an Internet protocol before any Unix people implemented it. The earliest DARPA Internet RFC I can find mentioning the DNS is RFC 830. There are, of course, quite a few RFC's subsequent to that, discussing refinements and changes to the protocol. The man page for named on my (Berkeley-like) system references RFCs 882, 883, 973 and 974. I believe that Berkeley was the first "vendor" to implement Unix software to deal with the DNS protocol. I suspect that most vendors' implementations are derived from the Berkeley implementation.
