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? Cheers, David.
