I think the first RFC having support for zoned IPv4 addresses in the network management world was RFC 2851 (published June 2000). I vaguely recall that we had several side meetings during the draft writing stage where people pointed to other work (that may have led to things like RFC 3927 later on) and/or they pointed out that the need to disambiguate IP addresses also exists in the IPv4 world. I think people also pointed to routers running multiple links using the same non-global (e.g., private) address spaces. /js -- Juergen Schoenwaelder Jacobs University Bremen gGmbH Phone: +49 421 200 3587 Campus Ring 1 | 28759 Bremen | Germany Fax: +49 421 200 3103 <https://www.jacobs-university.de/>
