This is fine if you are using AX.25 for link layer

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.
This concern is usually addressed through information in the whois database, which
includes, among other things, administrative and technical contacts for domain names. This
allows domain names to reflect what the service is, not who runs it or how it's
connected. This is how the internet and most local networks work, because this isolates
network topology changes and administrative changes from the users of the service, who
don't care about these details.
