Before deciding to implement DHCP, an administrator must first decide on an IP addressing plan. There are many different ways to create an IP addressing plan, and in some cases they may need to be combined. This is a critical step because it is the foundation of the entire DHCP infrastructure. This section looks into each of the different methods, describing their benefits, how they may be implemented, and some of their limitations.
Static IP Addressing
In an environment that uses static IP addressing, when an administrator installs a new workstation, she looks up an available IP address and the corresponding subnet mask in the IP address table. This table may be written in a notebook or saved on a computer in a spreadsheet. Once she finds the IP address, she needs to determine the correct DNS and WINS server addresses for the workstation to use. In addition, in a routed environment, the administrator needs to ascertain the correct default gateway address for the workstation’s subnet. Then she manually configures the workstation with the proper TCP/IP information. For small networks or networks that do not experience many changes, this may be fine.
One of the downsides to this method of administering IP addresses is human error. If the administrator mistypes the IP address or subnet mask, the workstation may not have connectivity to the resources it requires. If the DNS or WINS server IP addresses are mistyped, the workstation will not be able to perform ...
