Lexmark What is an IP address?, What is TCP/IP?, How do I locate IP addresses?

The MAC address of the internal print server is a series of letters and numbers. Other devices sometim es use a type
of MAC address called Universally Administered Address (UAA).
MAC: XX XX XX XX XX XX UAA: XX XX XX XX XX XX
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 and
you want to add a printer to your network, then 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 use d by devices (such as a wireless pr inter, computer, or wireless acc ess 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, an d other devices are able to send data to ea ch other,
either through cables or by using wirel ess signals. This transfer of dat a is made possible by sets of data trans mission
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) i s 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 commun icate must have an IP a ddress. IP addresses a re essentially
unique computer names in a numeri c format, used to transfer d ata around a network. IP addresses allow TCP/IP to
confirm requests for and receipt of data by various devices on the network.
