Dynamic DNS (DDNS) is a service that allows users to assign a static domain name to a dynamic IP address system. This technology is extremely useful for people and organisations who need to access their devices or services on a network that is behind a changing IP address.
In the traditional Internet Protocol (IP) system, each connection, be it a computer, router or other device, is assigned a unique IP address. This address enables identification and communication between devices on the network and on the Internet. However, most users receive dynamic IP addresses from Internet Service Providers (ISPs), which can change regularly. This can be an obstacle if you want to access a device or service from outside that is located in a network with a dynamic IP address.
This is where Dynamic DNS comes into play. DDNS services such as XServe-IT! offer users the ability to assign a static domain or subdomain to their dynamic IP address system. This allows users to access their devices or services via an easy-to-remember domain, regardless of whether their IP address changes or not.
