This is fine if you are using AX.25 for link layer media, but I don't see
AX.25 being the only link layer used on AMPRNET by a long shot. 802.11 is
growing in use and other link layer technologies exist. While info from
DNS may not meet a requirement for Identification requirement, having the
callsign of the party responsible (either directly as in the case of a
gateway, or indirectly as in the case of an ISP) for the host required as
part of the FQDN is helpful in tracing network issues.

Not that I am aware of. The IP traffic has NEVER required any callsign
identification. Nor has the TCP traffic. Transmissions over the air are
always carried atop layer 2, which is the AX.25 Link Layer protocol. The
transmitters on each end of every radio link use the callsign to identify
each and every frame sent over the air. Our callsigns are used in AX.25
Link Layer in the same way that MAC addresses are used in the 802.3
ethernet layer 2 / link layer protocol. Take a look at your ARP table to
confirm this.
The "transmitters" must be identified, and they may identify *within*
the published protocol (in this case AX.25). This is all that the FCC
requires.

the DNS functionality is a separate module and
is not tied to the name
of
the IP/subnet, not everyone uses their callsign as the DNS name
But that is a license requirement! We need a mapping between IP address
and callsign for legal use of IP on amateur radio....
