"On Linux, there are a number of DNS and DHCP servers, but two that work hand-in-hand are ISC’s BIND and DHCPd. Together, you can create a system where a client system obtains an IP via DHCP and will automatically have a DNS name assigned to it.

"In other words, if you connect a laptop to the local network, you need do nothing more than configure it to use DHCP; once it has connected, any other computer in the network will be able to ping or connect to it by merely using its hostname. This is commonly known as dynamic DNS. In this tip I’ll look at configuring the BIND side of a dynamic DNS service, and in a following tip I’ll configure the DHCP side and put it all together. The configuration here is used on a CentOS 5.3 system, but with some potential path changes, it should work on any Linux distribution."
