What is an IP address?
An IP address is a unique number used by devices (such as a wireless printer, computer, or wireless access
point) on an IP network to locate and communicate with each other. Devices on an IP network can
communicate with each other only if they have unique and valid IP addresses. A unique IP address means
no two devices on the same network have the same IP address.
An IP address is a group of four numbers separated by periods. An example of an IP address is
192.168.100.110.

How are IP addresses assigned?
An IP address may be assigned automatically by the network using DHCP. Once the printer is set up on a
computer, the computer sends all print jobs across the network to the printer using this address.
If the IP address is not automatically assigned, you will be asked during wireless setup to manually enter
an address and other network information after selecting your printer from the available list.
