Dynamic DNS
AVM Access Server – 5 AVM Access Server Concepts and Functional Principles 95
5.8 Dynamic DNS
Dynamic DNS is an Internet service that allows the AVM Access Server
to be continuously identifiable by a constant domain name even when
it does not have a constant public IP address.
Dynamic DNS is offered by both free and commercial providers. The
AVM Access Server supports two dynamic DNS providers, “Dynamic
DNS Network Services” and “companity, Andreas Wilkens”.
In order to use this service for your AVM Access Server, you must regis-
ter with one of these two dynamic DNS providers. Registration gives
you a fixed domain name and the access information for the dynamic
DNS server. Enter this information in the AVM Access Server configura-
tion on the “Gateway Services” dialog page in the “Internet” folder.
Each time the Internet connection is activated, the AVM Access Server
automatically informs the dynamic DNS provider of the current IP ad-
dress to be assigned to its domain name.
If you want to set up VPN Connections with the AVM Access Server, but
do not have a fixed IP address, you must use dynamic DNS in order to
identify the AVM Access Server by its domain name in the remote site’s
VPN connection configuration.
5.9 Windows Name Resolution and File and
Printer Sharing
The NetBIOS Name System
Windows networks today generally use IP, the Internet Protocol. In IP
communication, computers are addressed by four-byte numbers, such
as 192.168.10.1. Numeric IP addresses are difficult for human users to
work with, however. In Windows networking, mechanisms are provided
to map IP addresses to NetBIOS names.
The NetBIOS interface, used by Windows File and Printer Sharing, al-
lows resources such as computers, drives and printers to be accessed
by alphanumeric names. The network browsing service, which allows
the Windows Explorer to list the shared resources on all computers in a
LAN, is also based on NetBIOS.
