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

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.
