IP Address
Dimyas, launch the System Preferences application from the Apple menu and click on the "Sharing" pane; the IP address currently assigned to the machine you're on will be displayed toward the bottom of the window in the middle. If you are fortunate to have a static IP address, write it down and you'll always have it. If you IP address is dynamically assigned, it will change every time you close and reopen your IP connection. With a modem, this is every time you dial in. If you have broadband, it's every time you unplug your cable modem/DSL router/whatever, so, if you want to maintain the same IP address, just don't unplug your broadband device; it will give you the same IP address every time you restart your computer as long as the broadband device itself is left on.

SYNOPSIS
count] interface_name
DESCRIPTION
the Reverse Address Resolution Protocol client, implements the client portion of the Reverse Address Resolution Protocol (see It sends RARP
requests for the specified interface's hardware address and waits for the response from the RARP server. can be used during boot-time ini-
tialization to find the IP address of an interface. To do so, set the i] variable of interface i with in
Options are:
Print debugging information.
Use ethernet encapsulation only.
Use SNAP encapsulation only.
Transmits count requests and waits for each one to time out before
giving up.
interface_name Identifies the interface to request information about.
If a response is received, it prints the IP address to its standard output. This information can be used to configure the interface as
seen in
If a response is not received, the client will retransmit after 2 seconds, and then after 4 seconds. After that, retransmissions occur
every 8 seconds.
RETURN VALUE
Exit status is 1 if the command fails or no RARP response is received. Exit status is 0 and the IP address is printed to standard output
if a response is received.
LIMITATIONS
1. The client cannot be run at the same time a daemon is running on the same interface.
2. The client supports only ethernet, 100VG and FDDI network interfaces.
