RFC (Request for Comments) document: RFC 791 http://www.ietf.org/rfc/rfc0791.txt, Internet Protocol (September 1981)
This is often mistakenly attributed to Jon Postel, but it is actually a very slight variation on a quotation from John Shoch; both RFC-791 and its earlier version RFC-760 include, at the point in the text where this passage appears, a reference to Shoch's paper Inter-Network Naming, Addressing, and Routing, which is the original source of this observation.
