Protocol Configuration Items

TCP/IP Configuration

• 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.
