Section IV - TCP/IP 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 daemon is called rarpd. A name can be assigned to any device on a network and is arbitrary. For the following examples the name used for the OkiLAN 6010e is OKIPRINTER. Remember that this name is arbitrary; a customer can assign any name. /etc/hosts: The "/etc/hosts" file is where each entry maps a host name to an IP address. An example entry is shown below. 192.168.42.55 OKIPRINTER IV - 76 OKI OkiLAN 6010e User's Guide
