While I personally prefer a combined DHCP+DNS server like dnsmasq, you can also take a look at the whole Zeroconf/MDNS/Avahi/Bonjour stack. I'm not really sure if you can configure common devices and Linux PCs to use the DNS server for internet addresses and MDNS for local ones. In theory, it should be possible since you can distinguish them (local addresses should not be fully qualified _or_ have the domain .local). net-misc/mDNSResponder, sys-auth/nss-mdns and net-dns/avahi are probably good starting points.
