You can set most recent consumer router/gateway boxes to assign a static IP through DHCP when it recognizes a MAC address. This way, you can still have your laptop set up for automatic IP discovery through DHCP, but at home, you always get the same IP address, and the laptop is none-the-wiser. With regards to setting up an DNS server, it's trivial to set up simple DNS, but it can be somewhat challenging to set up reverse DNS for a first-timer. Not all router/gateway boxes support overriding just the DNS server address when handing out IP addresses via DHCP, though. My Zyxel P-330W allows this, and it works really well. Windows and Linux boxes can be set up easily to register their IP addresses with their DNS server when they receive a DHCP ack, so it can reverse the mapping as needed. IP-to-hostname resolution is called reverse DNS, which is what you need for dynamic IP clients to resolve correctly with traceroute and nslookup, among other things. So, the typical alternative is to run DNS and DHCP from a single Linux box instead of your router, which gives you the safest mechanism for updating the reverse DNS. There's a security hole there if someone else logs into your network and pretends their IP maps to one of your other machine names and is trusted to update that by the DNS server... If you run DHCP and DNS on the same machine, the clients don't need to register themselves because DHCP can tell DNS directly using only the loopback port. There are plenty of HowTo's out there for DNS, in case you want a weekend project, though. :-))) But, by far, the simplest solution is to use a static assignment from DHCP.
