[systemd-devel] [PATCH] sd-dhcp: implement IPv4 link-local support

[David Timothy Strauss]

This is a lot of code, and this approach is largely obsoleted by
link-local IPv6 addressing, which also has the benefits of being
simpler, deterministic (at least with RFC 4862), and collision-proof.
Both Apple [1] and Microsoft [2] prefer IPv6 link-local as the best
practice.

Is it really that important to support self-assigned IPv4?
