            What is DDNS (Dynamic DNS) ?

            In the dynamic world of the internet, where IP addresses can change frequently, Dynamic DNS (DDNS) plays a crucial role in keeping your online presence accessible and consistent. DDNS is a technology that automatically updates your domain name servers (DNS) with your current IP address.Β 

            This is useful for users who want to access their home computers, automation system, cameras, servers, or other devices remotely, but do not want to buy a valid (Fixed) IP address. With dynamic DNS, they can assign a hostname or domain name to their dynamically changing IP address, allowing them to access their devices using a consistent, easy-to-remember address.

            Keep in mind that all Internet providers usually use a dynamic IP for subscribers, which changes periodically, unless you buy a static IP (Valid).

            How DNS Works?

            In order to understand DDNS, you must first understand the concept of DNS(Domain Naming System). Imagine having to remember a unique IP address for every website you visit. That would be a daunting task! Instead, we use domain names, which are like nicknames for websites. But how do computers know which IP address corresponds to a particular domain name? That’s where DNS (Domain Name System) comes in.Β 
            DNS is like the internet’s address book. It translates domain names into IP addresses, allowing us to access websites by typing in their names instead of their numerical addresses. DNS servers work together to store and retrieve this information, making it possible for us to surf the web seamlessly.

            What is DDNS and How Does it Work?

            Dynamic DNS (DDNS) is a mechanism that dynamically updates the DNS records associated with your domain name (host name) to reflect your current IP address. This is crucial for maintaining seamless access to your online resources, even when your IP address changes, which is common for home internet connections.

            The Anatomy of a DDNS Transaction

            1- IP Address Acquisition: Your device connects to the internet and receives an IP address from your ISP (Internet Service Provider).

            2- DDNS Update Request: Your DDNS client software, typically running on your router or a dedicated DDNS-enabled device, detects the change in IP address and triggers an update request.

            3- DDNS Server Communication: The DDNS client software establishes a connection with the DDNS provider’s server.

            4- DNS Record Update: The DDNS client software communicates the new IP address to the DDNS server, which updates the corresponding DNS records associated with your domain name.

            5- DNS Resolver Interaction: When a user enters your domain name in a web browser, their request is sent to a DNS resolver, which acts as a directory of IP addresses for domain names.

            6- DNS Resolver Lookup: The DNS resolver retrieves the updated DNS records from the DDNS server and associates your domain name with your current IP address.

            7- User Redirected to Updated IP: The DNS resolver sends the user’s request to your updated IP address, ensuring they access the correct server or service.
