it's very much worth re-reading RFC 921 and RFC 952 to understand how it was that domain-style names (an RFC 952 term, which RFC 921 described as "structured names" or "hierarchical names") preceded what we today call the "domain name system."
I'm struggling slightly on the logic here, although I was not around at the time these documents were written so my perspective may be skewed.
RFC 952 and RFC 921, if I read them correctly, define "structured names" (or the synonymous "domain style names") as part of a _transition_ from a flat namespace to ("a" | "the") "Domain Name System".
STD 13 then effectively makes udp/53 and tcp/53 the de-facto wire protocols for interrogating that system, mostly surplanting the use of host files.
On that basis, I'm unable to separate the RFC 921 / 952 "Domain Name System" namespace from the STD-13 one embodied in the ICANN-managed root zone that we have now. I think they're the same thing.
