I don't think this idea of link-local as currently specified will work. An IPv4 link-local address has a dedicated IP range and is used in case static IP is not configured and DHCP failed. So it cannot reliably be used to determine if a node is on the same LAN. It is very uncommon that a device has a static/DHCP IPv4 address and a link local address. According to RFC 3927 Section 2.1, an IPv4 device should not keep both addresses active at the same time because it introduces unnecessary routing table complexity.
The situation with IPv6 is totally different but then we have to specify that IPv6 addresses must be used by the endpoint.

We've decided that the LAN check is not necessary, since there is no inherent security risk if a node claims to be in the LAN, but is not. The specification does need to explain this explicitly. |
