Dynamic DNS
Dynamic DNS menu
The DIR-120 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.
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.
