IP Addresses
Every device on a network has an address, called its IP (Internet Protocol)
Address. This address allows the network to identify each device and direct
information to the correct devices.
Each network has a specific range of addresses that is valid for that network. A
device that is configured for one network will generally not work on another
network, because its IP address is not in the network’s valid range.
IP Addresses can be static or dynamic. Static addresses never change, and are
used for devices that must remain at the same address, such as printers and other
peripheral devices. Dynamic addresses are assigned to a device temporarily and
can change.
In order to connect new devices to the network, a Dynamic Host Configuration
Protocol (DHCP) is used. DHCP recognizes when a new device is attached to the
network and assigns an address to the new device from a pool of addresses that
are allocated for DHCP. A dynamic address assigned by DHCP is called the
device’s DHCP address.
For a device that requires a static address, the Network Administrator must
allocate a specific address to ensure that no other devices on the network use the
same address. In order to work properly, the Network Administrator must assign a
static address and the device must be set to use that static address.
