IP address overview
What is an IP address?
Each device (such as a computer) which participates in an IP network needs a unique
"address" on the network. It's similar to having a US mail address so other people
have a know way to send you messages. An IP address is a four byte number, which
is usually written in "dot notation" - each of the bytes' decimal value is written as a
number, and the numbers are separated by "dots" (aka periods). An example:
199.25.123.1
How do I get one for this box?
The IP addresses on most modern corporate nets are assigned by an employee
called a "Network Administrator", or "Sys. Admin". This person assigns IP addresses
and is responsible for making sure that IP addresses are not duplicated - If this
happens one or both machines with a duplicate address will stop working.
Another possibility is getting your address assigned to you automatically over the net
via DHCP protocol. Enable DHCP function, and reset the machine. If your network is
set up for this service, you will get an IP address assigned over the network. If you
don't get an address in about 30 seconds, you probably don't have DHCP.
IP Configuration
The IP Configuration includes the IP Address, Subnet Mask and Gateway. The
Configured column is used to view or change the IP configuration. Fill up the IP
Address, Subnet Mask and Gateway for the device. The screen in Figure 4-8 appears.
