DNS
Domain Name System
Hierarchical system that permits the assignment of IP addresses to Domain names that
are easier to note. This assignment has to be managed by a local DNS server in each
(W)LAN. The local DNS server determines the IP address, if necessary by enquiring about
superordinate DNS servers and other local DNS servers on the Internet.
You can specify the IP address of the primary/secondary DNS server.

Dynamic DNS
Domain names and IP addresses are realised via DNS. For Dynamic IP Addresses this

ensures that a service can always be addressed on the Internet under the same Domain
name irrespective of the current IP address.
