Absolutely you would, and people do. This is described in the O’Reilly book “Zero Configuration Networking: The Definitive Guide” <https://www.oreilly.com/library/view/zero-configuration-networking/0596101007/> For an example closer to home, consider the IETF itself. For many years, IETF meetings provided a printer in the “terminal room”. The NOC staff added DNS records to describe that printer. This made the printer discoverable from any wired or wireless network in any of the IETF meeting rooms, not just from the local Ethernet in the terminal room. A step-by-step explanation of precisely how this worked is available here: <https://datatracker.ietf.org/doc/html/draft-cheshire-dnssd-roadmap-03#appendix-A> Stuart Cheshire _______________________________________________ DNSOP mailing list -- [email protected] To unsubscribe send an email to [email protected]
