Connectivity
Ethernet
Ethernet
Standardised transmission technology for wired networks with various transmission
speeds (10/100/1000 Mbit/s).
IEEE
Institute of Electrical and Electronics Engineers
Global professional organisation of engineers predominantly based in electrical engineer-
ing and information technology.
IP address
Internet Protocol address
Each network that is connected to the Internet is assigned a globally unique IP address.
The function 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 as-
signed. The protocol IPv6 was introduced to cover the additional demand. Both IPv4 and
IPv6 are used in parallel today.
IPv4 4 blocks made up of numbers between 1 and 255, separated by points.
A maximum of 2
Example: 173.194.0.155
IPv6 8 blocks made up of 4 digits, separated by colons (hexadecimal system).
A maximum of 2
Example: 2001:0638:a000:3501:0230:7000:c000:d76e
Subnet The subnet mask separates the network address into a network component and
mask a device component, in the same way that a forward slash (/) separates the area
(IPv4) 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:

172.16.232.15
Prefix Corresponds to subnet mask.
