How many hosts does it take to justify the time and effort to setup a centrally, managed solution for name resolution and address allocation? ( in other words, is it worth setting up DHCP for 2 computers? 5? 25?
I believe one host is enough. In fact, if the host has a functioning network interface which is connected to a network chances are it is managed by DHCP uses DNS for name resolution. Although most end users don’t know or understand the how their computer connects to the Internet and never realize their computer is being managed by the router/gateway installed by their ISP which perform the roles of DHCP and DNS servers. I prefer to manage the IP address received by my computers at home by making reservations that way I always know the IP addresses of various hosts on my home network.
