OkiLAN 6200e Plus User's Guide do not know their IP address. When powering up on a network, a device that uses RARP broadcasts its network hardware address in a RARP request message. A RARP server (which may be a UNIX workstation) responds with an IP address. The device then knows its IP address and use this address to perform subsequent TCP/IP transactions. Note: Once the Network Print Server has been assigned an IP address, the Network Print Server configuration utility (which is accessed by telneting to the Network Print Server) or OkiNet for TCP/ IP allows you to change and/or make the IP address permanent. This means that a RARP server needs to be available only during installation of the Network Print Server. Address Formats Network hardware addresses are 48-bits and are expressed in 6 bytes in hexadecimal format usually separated by colons. Each hexadecimal byte has a range from 00 to FF. Example: 00:02:16:17:50:A4 IP addresses are 32-bits and are expressed in 4 bytes in decimal format usually separated by periods. Each decimal byte has a range from 0 to 255. Example: 192:168:42:55 Configuration Files The purpose of RARP is to look up a 32-bit IP address given a 48-bit network hardware address. The RARP server (which is usually a UNIX workstation running a rarpd daemon) performs this function using two configuration files and one or more daemons. The configuration files are "/etc/hosts" and "/etc/ethers" and the TCP/IP 142
