Should I Enable DDNS? Here Are the Top Use Cases

The use cases for DDNS typically stem from internet connectivity issues of one type or another. 

Dynamic DNS (DDNS) is a service that automatically updates the DNS registry whenever a device’s IP address changes, ensuring constant connectivity. The technology has many use cases. 

Common DDNS use cases 

Businesses that sell internet-connected household devices leverage DDNS because their products often rely on established consumer-grade internet connections. In most cases, consumer internet services offer only rolling IP addresses. In order to maintain connectivity, businesses must be aware of the IP address of the customer. Remote monitoring and security companies, for example, rely on the connectivity of the home or business they’re serving. If the customer doesn’t have a static IP address, they must either procure one or enable DDNS to overcome this obstacle. 

Organizations with devices that move locations and connect to different networks leverage DDNS to maintain knowledge of the devices’ IP addresses regardless of geography. Cellular connectivity is a common implementation in many industries, such as transportation, mining, and energy. If an organization is operating in a remote location, connectivity may be limited, but DDNS can be used for connected devices to ascertain real-time information or provide updates.  

A rural, corrosive environment 

In one case, a wastewater company wanted to enable DDNS in its plants, which each had servers that required constant connectivity for updates, monitoring, troubleshooting, etc. But because of their rural locations, the company couldn’t assign static IP addresses to the servers. 

To complicate matters, the servers were in corrosive environments. They were exposed to high levels of chlorine gas and moisture, which destroy electronics. These appliances are extremely expensive, because they are environmentally hardened servers. As such, these servers had somewhat limited functionality, because they were so specific in nature. 

The wastewater company was looking to establish remote connectivity to these locations without putting more hardware in place. They needed a software-based approach that was reliable, durable, and easily implemented and managed. 

With Oracle Dyn, organizations can enable DDNS simply by downloading our agent onto their servers, which maintains the servers’ IP addresses and allows for constant connectivity.  

Other dynamic DNS considerations 

The need for DDNS is also greater in remote locations or small towns where you simply don’t have a lot of static IP addresses that can be assigned. Cost is another factor. A static IP address could cost hundreds of dollars per month, which many small businesses can’t justify.
