Subnet masks restrict network communication.
| • | Example: Computer 1 can talk to Computer 2 | • | Computer 1 IP Address: 192.168. 1. 2 Subnet Mask: 255.255.255.000 | | • | Computer 2 IP Address: 192.168. 1. 3 Subnet Mask: 255.255.255.000 |
|
Where the 0 is in the Subnet mask, there is no limit to communication at this part of the address. What this means in the above example is, we can communicate with any device that has an IP address that begins with 192.168.1.x. (where x.x. are numbers between 0 and 255).
