RFC 8200: Internet Protocol, Version 6 (IPv6) Specification<https://www.rfc-editor.org/rfc/rfc8200.html#page-5>
host         any node that is not a router.

RFC 9198 - Advanced Unidirectional Route Assessment (AURA)<https://datatracker.ietf.org/doc/html/rfc9198#name-terms-and-definitions>
Host A Host (as defined in [RFC2330<https://datatracker.ietf.org/doc/html/rfc2330>] is a computer capable of IP communication, including routers (aka an RFC 2330 Host)
The word "host" is used in IPPM without any qualifier, no "RFC 2330 host", just "host" - like for 6man.

IMHO: It is better to rename the "host" in IPPM because:
RFC 1122 - Requirements for Internet Hosts - Communication Layers (October 1989)<https://datatracker.ietf.org/doc/html/rfc1122#page-6>

A host computer, or simply "host," is the ultimate consumer of

         communication services.  A host generally executes application

         programs on behalf of user(s), employing network and/or

         Internet communication services in support of this function.

         An Internet host corresponds to the concept of an "End-System"

         used in the OSI protocol suite [INTRO:13]

By the way, "node" is different too for these 2 basic documents, but not the opposite meaning like the host. It is better to unify too.

It would be good to have one "terms and definitions" RFC for the whole IETF.
