- 127 -Setting IP Address5 5. Network Settings Setting IP Address What is IP address?For connecting a computer and printer through a network by using TCP/IP, IP addresses need to be setup. IP addresses are the addresses of computers and printers on the network. If an IP address is notset correctly, the computer and printer cannot communicate because the address to send data to is notspecified.Memo● For the connection with a Macintosh through a network, EtherTalk protocol is used. In this case, IP address setting is notrequired.● For using a web browser in the Macintosh environment, set the IP address.IP address :192. 168. 0. 3Network address Host IDSubnet mask :255. 255. 255. 0Gateway :192. 168. 0. 1IP address :192. 168. 0. 2Network address Host IDSubnet mask :255. 255. 255. 0Gateway :192. 168. 0. 1ComputerPrinter(Example)Not any numbers or values can be used for the IP address. There is a rule to specify the IP address.An IP address has 4 segments and each segment consists of 3-digit number. In the example above,“192. 168. 0” is the portion called the “network address”, and the last segment, such as “3” or “2” inthe example, is the portion called the “host ID”. In the general network, the network address of thecomputer and printer needs to be the same to communicate. The host ID needs to be specified byusing a unique number for each device within the range from 1 to 254.In addition to the IP address, the subnet mask and gateway also need to be set up. Basically, set thesubnet mask to “255. 255. 255. 0”. Use the IP address of the router in the network for the settingof the gateway. For a general network configuration, use the same subnet mask and gateway for thecomputer and printer.
