DIR-100 Ethernet Broadband Router
Dynamic DNS
The DIR-100 supports DDNS or Dynamic Domain Name Service. Dynamic DNS allows a dynamic public
IP address to be associated with a static host name in any of the many domains, allowing access to a specific
host from various locations on the Internet. With this function enabled, remote access to a host will be
allowed by clicking a URL hyperlink in the following form: hostname.dydns.org Because many ISPs assign
public IP addresses using DHCP, it can be difficult to locate a specific host on the LAN using the standard
DNS. For example, if you are running a public web server or VPN server on your LAN, DDNS ensures that
the host can be located from the Internet if the public IP address changes. DDNS requires that an account be
set up with one of the supported DDNS servers.
D-Link offers a free DDNS service. If you are interested in using D-Link’s DDNS service, click the
hyperlink to www.DlinkDDNS.com
to sign up.
Dynamic DNS menu
To implement Dynamic DNS, first tick the Enable DDNS checkbox in the window above, then choose the
Server Address from the list in the pull-down menu. Next, enter the Host Name of the LAN to be accessed,
and the Username and Password for the DDNS account. Click the Save Settings button to save changes
made. Use the DDNS Account Testing button to make sure the DDNS service is functioning.
