DNS Server If you have not been given specific DNS server IP addresses or if the Router is not pre-configured with DNS server information, tick the Enable Automatic Assigned DNS checkbox. Auto discovery DNS instructs the Router to automatically obtain the DNS IP address from the ISP through DHCP. If your WAN connection uses a Static IP address, auto discovery for DNS cannot be used. If you have DNS IP addresses provided by your ISP, deselect the Enable Automatic Assigned DNS checkbox and enter these IP addresses in the available entry fields for the Primary DNS Server and the Secondary DNS Server. Click the Save button when you are finished. Dynamic DNS The Router supports Dynamic DNS (Dynamic Domain Name Service). The Dynamic DNS service allows a dynamic public IP address to be associated with a static host name in any of the many domains, allowing access to a specified host from various locations on the Internet. This is enabled to allow remote access to a host by clicking a hyperlinked URL in the form hostname.dyndns.org, Many ISPs assign public IP addresses using DHCP, this can make it difficult to locate a specific host on the LAN using standard DNS. If for example you are running a public web server or VPN server on your LAN, this ensures that the host can be located from the Internet if the public IP address changes. DDNS requires that an account be setup with one of the supported DDNS providers. Click Add to see the Add DDNS Settings section.
Section 3 – Configuration D-Link DSL-2650U User Manual 64 Enter the required DDNS information, click the Save/Apply button to save the information. Note DDNS requires that an account be setup with one of the supported DDNS servers prior to engaging it on the Router. This function will not work without an accepted account with a DDNS server.
