The acronym "DDNS" stands for "Dynamic Domain Name Service." Several online companies offer DDNS, providing clients the ability to use one domain name regardless of the dynamic (changing) IP address of their web application. DynDNS.com, DNS2go.com, and No-IP.com are all examples of companies that provide DDNS service. Some companies offer free basic versions of their DDNS products, while charging a fee for enterprise-level and corporate service. Research the available DDNS services to find a service to meet your specific needs. DDNS is easy to use and may be configured in a few steps.

Things you need
- Computer with Internet access
- Website or Web application with corresponding domain name, operational and accessible on the Internet
Select the best DDNS service for your needs (see Resources).
Open a Web browser and enter the URL for the site of the chosen provider.
Create a new user account with the DDNS provider.
Download and install the DDNS client software.
Navigate to the Configuration page of the DDNS provider. The DDNS will be configured over the Internet, and the client application will access the configuration based upon the user's account credentials.
Enter the hostname for the website or Web application in the "Hostname" input box.
Check the "Wildcard?" checkbox to facilitate wild cards.
Type an entry for the input box labelled "Time To Live" (TTL). This value indicates how long the site hostname will be cached on the server.
Check one of the following service types: "A-Record Pointed to IP Address," "Offline Hostname," or "Webhop Redirect".
Select the "Auto-detect" option checkbox to automatically detect the IP address of the computer via the client application, or manually type an IP address into the input box. (This step is not necessary with the Webhop Redirect option.)
Type a URL for the "Redirect URL" input field. The Redirect URL is the domain name or IP address of the destination website or Web application. (This step is not necessary with the A-Record to IP Address selection.)
Check the checkbox labelled "Cloak the Page" to conceal the actual destination URL and replace it with the dynamic domain name provided by the DDNS.
Type a "Cloaked Page Title" in the input box, if this option was selected.
Set the Mail Options for the new dynamic hostname in the section labelled "Mail Options."
Click "OK" and save the configurations.
Open a browser and navigate to the administration page for the network router on which the website or Web application is hosted.
Click "Port Forwarding" and open a port for the DDNS, if needed. (This step is not necessary on most networks.)
Test and verify the connection of the new DDNS domain name from another computer with Internet access.
