The MAC address is a series of letters and numbers located on the back of your printer.
Note: A list of MAC addresses can be set on an access point (router) so that only devices with matching
MAC addresses are allowed to operate on the network. This is called MAC filtering. If MAC filtering is enabled
in your access point (router) and you want to add a printer to your network, the MAC address of the printer
must be included in the MAC filter list.
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.
What is TCP/IP?
Networks are able to function because computers, printers, and other devices are able to send data to
each other, either through cables or by using wireless signals. This transfer of data is made possible by sets
of data transmission rules called
protocols . A protocol can be thought of as a language, and like a language,
it has rules allowing participants to communicate with each other.
Different types of networks use different protocols, but Transmission Control Protocol/Internet Protocol
(TCP/IP) is the most popular. TCP/IP is used to send data over the Internet as well as over most corporate
and home networks.
Because computers do not understand words and instead rely upon numbers for communication, TCP/IP
requires that every device on a network using TCP/IP to communicate must have an IP address. IP addresses
are essentially unique computer names in a numeric format, used to transfer data around a network. IP
addresses allow TCP/IP to confirm requests for and receipt of data by various devices on the network.
