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 |
|
Note
| | 0 denotes that there is no limit to communication at this part of the address. |
In the above example, we can communicate with anything that has an IP address that begins with 192.168.1.x. (where x.x. are numbers between 0 and 255.)
