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.

do not
know
their IP address. When powering up on a
network, a device that uses RARP broadcasts its net-
work 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 subse-
quent 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 telnet-
ing 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 installa-
tion 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 config-
uration files and one or more daemons. The configura-
tion files are “/etc/hosts” and “/etc/ethers” and the
