Off topic, but actually DHCP is still needed. A machine needs to
configure a lot more than just its address and router in common cases
(it wants things like DNS servers, NTP servers, etc.) and in large
deployments, it is often far easier to let machines autoconfigure these
things during boot using DHCP even on comparatively hard wired
networks.
And with that, lets return to crypto...
