dynamic dns (DDNS) is a service that automatically updates the DNS records for a domain when the IP address changes. This is particularly useful for devices that do not have a static IP address, such as home networks or small businesses. While static IP addresses are typically more reliable and easier to manage, they can be expensive and not always necessary for every use case. DDNS services provide a cost-effective solution by ensuring that your domain name always points to the correct IP address, even if it changes frequently.

What is a DDNS Service Provider?

A DDNS service provider is a company that offers dynamic DNS services to its clients. These providers maintain a constantly updated database of domain names and their corresponding IP addresses. When an IP address changes, the provider automatically updates the DNS records to reflect the new IP, ensuring that the domain name continues to function correctly. This is especially important for services that require constant connectivity, such as remote access, web hosting, and security cameras.

How DDNS Works

Dynamic DNS works by using a client-side application or a built-in feature in routers to periodically check and update the IP address. When a change is detected, the client sends the new IP address to the DDNS service provider, which then updates the DNS records accordingly. This process is seamless and typically happens within a few minutes, ensuring minimal downtime for the user.

Key Features of DDNS Service Providers
