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 two hosts are 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. Most end users
don’t know or understand 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.
