IP address
Internet Protocol address
Each network that is connected to the Internet is assigned a globally unique IP address. The func-
tion of the IP address is the same as that of a telephone number in a telephone network.
Due to the rapid development of the Internet, all possible IPv4 addresses have been assigned. The
protocol IPv6 was introduced to cover the additional demand. Both IPv4 and IPv6 are used in par-
allel today.
IPv4 4blocks made up of numbers between 1 and 255, separated by points.
A maximum of 2
32
(approx. 4.3billion) addresses are possible.
Example: 173.194.0.155
IPv6 8blocks made up of 4 digits, separated by colons (hexadecimal system).
A maximum of 2
128
(340sextillion) addresses are possible.
Example: 2001:0638:a000:3501:0230:7000:c000:d76e
Subnet
mask
(IPv4)
The subnet mask separates the network address into a network component and a
device component, in the same way that a forward slash (/) separates the area code
from the local telephone number.
The network component must be the same for all devices within a network. The device
component is different for each device within a network.
There are 5 network classes (A–E). Only network class C is used for private use.
Examples:
Network address Subnet mask Usable address range
192.168.7.11 255.255.255.0 192.168.7.1–192.168.7.254
172.16.232.15 255.255.0.0 172.16.0.1–172.16.255.254
