The use cases you’ve described are remarkably similar to those used for https://www.gs1.org/standards. In practice, there are many reasons why systems like these were not universally accepted, not least were privacy-related and the fact that many in industry didn’t like the idea of their products being identified in a global registry. > Technically speaking, the IPv6 address is assigned to a node hosts a page > (URL/FTP/whatever) containing the information about a non-electrical object. > The IPv6 address is always connected (online) and respond to any query from > the Internet.

Since there has to be a gateway to represent/proxy/translate for non-connected objects, why not use a (free) PEN or a (free) self-generated UUID instead of (e.g.) having to pay yearly for an IPv6 prefix that will never be directly routed? > RFC1881 - “IPv6 Address Allocation Management” created in 1995 defines how > IPv6 will be allocated […] There is NO mention of IPv6 could not be used for > non-electrical items. > RFC4291 - “IP Version 6 Addressing Architecture” created in 2006 provides > guidance on how to use IPv6 in the networks.

There is an argument that can be made that IoT devices can/should be numbered with IPv6 as it seems likely that (eventually) the cost of hardware/software/power/etc. for implementing a full TCP/IP stack will fall sufficiently for it to make sense to use it instead of different/simplified protocols, although those devices should obtain their addresses via SLAAC/DHCPv6 to ensure routability. This obviously doesn’t apply to non-connectable objects. Regards, -drc
