I agree with that sentiment. But what is strange about my setup?
Perhaps you can help me find a less idiosyncratic way.

Condition #1: All devices at home must be addressable by name.
Condition #2: Several devices cannot have a static IP address assigned.
For example, this PC is 192.168.1.17 at home. Currently it is 172.20.5.105;
last night it was 10.0.27.15.

So at home, all the IP addresses are assigned by the router using the
devices' MACs. The computers use /etc/hosts to look up other devices.
The non-"computers" use the router's IP address for their configuration.

What would you change?
