Please Whitelist This Site?
I know everyone hates ads. But please understand that I am providing premium content for free that takes hundreds of hours of time to research and write. I don't want to go to a pay-only model like some sites, but when more and more people block ads, I end up working for free. And I have a family to support, just like you. :)
If you like The TCP/IP Guide, please consider the download version. It's priced very economically and you can read all of it in a convenient format without ads.
If you want to use this site for free, I'd be grateful if you could add the site to the whitelist for Adblock. To do so, just open the Adblock menu and select "Disable on tcpipguide.com". Or go to the Tools menu and select "Adblock Plus Preferences...". Then click "Add Filter..." at the bottom, and add this string: "@@||tcpipguide.com^$document". Then just click OK.
Thanks for your understanding!

Host Configuration and TCP/IP Host Configuration Protocols (BOOTP and DHCP)
Each host that is placed on a network
or internetwork must be set up and configured before it can be used.
Configuration ensures that the host functions properly, and that it
is told the parameters needed for it to successfully communicate with
other hosts and devices. In the good old days, administrators
would manually set up each host as it was added to the network, and
would also manually make changes to the configuration as they were required.
Modern networks, however, are very large, and manual configuration of
hosts is a time-consuming chore. Furthermore, we often need to make
use of features that only automated configuration can provide, particularly
for special hosts that have no internal storage. It is for these reasons
that host configuration protocols were developed.
In this section I describe the concepts
behind host configuration protocols, and then illustrate the operation
of two of the most important ones in use today. I begin with a topic
that provides an overview of host configuration concepts and issues.
I describe the TCP/IP Bootstrap Protocol (BOOTP), the first truly capable
automated configuration tool for IP hosts. I then describe BOOTP's successor,
the feature-filled Dynamic Host Configuration Protocol (DHCP), which
is used extensively in modern TCP/IP hardware and software.
Related Information: Technically, the very first host configuration protocol for TCP/IP was the Reverse Address Resolution Protocol (RARP). RARP is a very simple, crude protocol that allows very basic host configuration to be performed, but little else. RARP is very different from BOOTP and DHCP, not only because of its more limited capabilities, but because it operates between layers two and three like the Address Resolution Protocol (ARP) upon which it is based. It is therefore covered in the same section that describes ARP.
