DynDNS
Dynamic DNS
The assignment of

Domain names

and

IP addresses

is handled by the Domain Name

Service (

DNS

). This service is now enhanced with so-called Dynamic DNS (DynDNS) for

Dynamic IP addresses

. This enables the use of a network component with a dynamic

IP address as a

Server

on the Internet. DynDNS ensures that a service can always be

addressed on the

Internet

under the same domain name regardless of the current

IP address.

Dynamic IP address
A dynamic

IP address

is assigned to a network component automatically by

DHCP

. This

means that the IP address of a network component can change with every login or at
certain intervals.

encryption and

WPA

encryption for secure data transmission over

wireless networks.

Ethernet
Ethernet is a network technology for local networks (

LANs

) defined by the

IEEE

as stand-

ard IEEE 802.3. Ethernet uses a baseband cable with a data transmission rate of 10 or
100

Mbps

.

Exposed Host
Exposed Host refers to a PC outside the firewall.

Firewall
Firewalls are used by network operators as protection against unauthorised external
access. This involves a whole bundle of hardware and software actions and technologies
that monitor and control the data flow between the private network to be protected and
an unprotected network such as the

Internet

.
