How a DUC works
1. Domain registration: first the user registers a domain name through a Dynamic DNS service. 2. Setup: next the user installs the client on their computer, on a router, or on any other device (IoT). This client sends the IP address update commands. 3. Monitoring for changes: the DUC periodically checks the current external IP address of the device it is installed on. 4. DNS update: when the client detects that the IP address has changed, it sends an update to the DynDNS servers to update the corresponding DNS record with the new IP address. 5. Access by domain name: thanks to dynamic DNS technology, users can keep connecting to services by domain even if the IP address has changed.
Types of DynDNS clients
Depending on the usage conditions, goals and properties of the environment, one or another DynDNS client may be used.
1. Desktop clients: - These are applications installed on users' computers (Windows, macOS, Linux). They watch for IP address changes and update the DNS records accordingly. - Examples: DUC from DynDNS and other third-party clients. 2. Routers with DUC support: - Some routers have built-in features for working with dynamic DNS. They let you configure a DUC in the router itself or in its web interface, which removes the need to install separate software on a computer. - Examples: many router models from TP-Link, ASUS, Netgear and others. 3. Scripts and utilities for servers: - For server systems (for example, Linux), there are scripts and command-line utilities that can automatically update DNS records. They can be written in various programming languages (bash, Python and others) and run as cron jobs. - Examples: bash scripts, Ansible, Python scripts. 4. Cloud solutions: - Some users prefer to use cloud services to manage dynamic DNS without installing a DUC on their devices. These solutions often integrate with other cloud services. - Examples: cloud router simulators or specialized hosting platforms that offer dynamic DNS as a service. 5. Mobile apps: - Some clients may be available as mobile apps that track the IP address of your mobile device or Wi-Fi network and update DNS to reflect those changes.
