If you want to hand configure your network, set up DHCP and disable SLACC. I wouldn't recommend it, because it just makes life harder, but you can do it. Even better though, hostname resolution works just fine on link local addresses (fe80::/16), you needn't care about public addresses to communicate on a LAN. Or hell, you're on a LAN, keep configuring IPv4 they way you always have.
