My openwrt router runs dnsmasq which reads these two files : /etc/hosts : association between ip and hostname /etc/ethers : association between mac and hostname When I add a box the my network, I just need to know its mac and add one line to these two files. Then I know which ip it will always uses, and I also know which hostname to use just by looking at the table. So in fact, I don't care much about the real hostname of the box (it's better if it matches but not necessary)
