There are multiple references to network byte order in RFC 3542, and it's very specific for raw sockets. That seems clear enough. RFC 1958 says: 3.13 All specifications should use the same terminology and notation, and the same bit- and byte-order convention. (sadly, without saying what i

After a little detective work: The concept of a 'standard' (Internet) network byte order appears to have crept into the RFC series without actually officially linking Appendix B of RFC 791 (dated Sptember 1981) to the term. AFAICS the earliest use of the term 'standard network byte order' is
