In theory, we can reserve `169.254.1.1` as default gateway (and default DNS server) for IPv4, to get rid of DHCP protocol. I'm doing so in my embedded project for network connection via USB, because it makes network configuration static.

Just a heads up for anyone confused about 169.254.1.1: 169.254.0.0/16 is the link-local address block for IPv4, but link-local addressing is rarely used in IPv4. OTOH, the fe80::/10 address block on IPv6 is widely known since link-local addresses are mandated by the standard.
