• IP Address
• Subnet mask
• Gateway (when routers exist on your network)
■ IP Address
An IP address is a series of numbers that identifies each computer
connected to a network. An IP address consists of four numbers
separated by dots. Each number is between 0 and 255. You must
allocate a unique IP address that is correct for the attached
network.
(Example) In a small network, set the IP addresses by changing
the final number.
192.168.1.1, 192.168.1.2, 192.168.1.3
■ Subnet mask
Subnet masks restrict network communication, see example
below -
(Example) PC1 can talk to PC2
PC1 IP Address 193. 1. 2. 3
Subnet Mask 255. 255. 0. 0
PC2 IP Address 193. 1. 3. 4
Subnet Mask 255. 255. 0. 0
Here is an example of an IP address and a subnet mask.
IP Address 193. 1. 2. 3
Subnet Mask 255. 255. 0. 0
In the above example, we can communicate with anything that has
an IP address that begins with 193.1.X.X
■ 0 denotes that there is no limit to communication at this part
of the address.
