CONFIGURING IP ADDRESSES

An IP address is a logical address assigned to devices in a computer network that uses the Internet Protocol (IP) for
communication between nodes. IP addresses are stored as binary numbers but they are represented using
Decimal Dot Notation, where four sets of decimal numbers are separated by dots as follows:
XXX.XXX.XXX.XXX
For example:
10.86.254.85
An IP address in a network is usually associated with a subnet mask. The subnet mask defines which network the
device belongs to. A subnet mask has the same form as an IP address.
For example:
255.255.255.0
Both the IED and the REB each have their own IP address. The following diagram shows the IED as IP1 and the REB
as IP2.
Note:
IP1 and IP2 are different but use the same subnet mask.
