Last octet is any unique number from 0 to 255 (there are restrictions on using 0 and 255 ,
Ÿ
so avoid using them). You would not use 1 as the last number, since that number is the
last octet in the EMTA IP address in our example.
Figure 5-2 shows an example of IP addresses assigned to devices on the network.
Figure 5-2. Example of IP Addresses for Networked Devices
You define the computer's IP address using the procedure appropriate for your operating
system, as described in Chapter 3.
Tip: The following Windows sections describe how to use the command-line program
Windows IP Configuration (ipconfig) to see the IP address of a computer running a Windows
operating system. However, if you want even more information, such as IP routing and DHCP
information, type ipconfig /all instead of ipconfig in the Windows sections that follow.
The most common problem associated when viewing IP addresses is that either:
A computer's IP address is not on the same subnet as the other networked devices. In
Ÿ
other words, the first nine numbers (three octets) in the device's IP address are not
identical to those of the other networked devices.
A computer shows an IP address that starts with the digits 169.254 . When this
Ÿ
happens, it often means the computer could not retrieve a network address from a
DHCP server and therefore automatically assigned itself an address from the base
