Transmission Control Protocol / Internet Protocol
These are languages by which network-able equipment such as computers, printers and iDR
communicate, commonly known as Ethernet or network. Each device on a network has its own
address. The address has four parts and we will compare them to country, city, street and house
number.

255 255 0
The
Subnet mask
determines which numbers are house numbers. In this example, all numbers
corresponding to 255 are country, street etc. Numbers corresponding to 0 are house numbers. This
allows up to 999 house numbers or devices on the network. A larger network can be set up by
having a subnet mask of 255.255.0.0. This would allow 999,999 devises on the network.
