The MAC address of the internal print server is a series of letters and numbers. Other devices sometimes use a typeof MAC address called Universally Administered Address (UAA).Note: A list of MAC addresses can be set on an access point (router) so that only devices with matching MAC addressesare allowed to operate on the network. This is called MAC filtering. If MAC filtering is enabled in your access point andyou want to add a printer to your network, then the MAC address of the printer must be included in the MAC filterlist.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) onan IP network to locate and communicate with each other. Devices on an IP network can communicate with eachother only if they have unique and valid IP addresses. A unique IP address means no two devices on the same networkhave 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 transmissionrules called protocols. A protocol can be thought of as a language, and like a language, it has rules allowing participantsto communicate with each other.Different types of networks use different protocols, but Transmission Control Protocol/Internet Protocol (TCP/IP) is themost 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 requiresthat every device on a network using TCP/IP to communicate must have an IP address. IP addresses are essentiallyunique computer names in a numeric format, used to transfer data around a network. IP addresses allow TCP/IP toconfirm requests for and receipt of data by various devices on the network.How do I locate IP addresses?For Windows users1 Click , or click Start and then click Run.2 In the Start Search or Run box, type cmd.3 Press Enter, or click OK.4 Type ipconfig, and then press Enter.The IP address appears as four sets of numbers separated by periods, such as 192.168.0.100.Networking81
