What is DDNS?

Dynamic DNS (DDNS) is a service that updates the DNS (Domain Name System) to reflect changes in a device’s IP address. This allows a device to be consistently reached using the same domain name, or hostname, even if its IP address changes.

Why Do You Need DDNS?

  • Consistency and Accessibility: Access your devices like security cameras or remote servers using the same hostname, regardless of IP changes.
  • Remote Access: Ideal for accessing home or office networks from anywhere.
  • Cost-Effective: Avoid the high cost of static IP addresses with DDNS.

How Does DDNS Work?

  1. Dynamic IP Address: Your ISP assigns a dynamic IP address that changes periodically.
  2. DNS Update: DDNS services detect these IP changes and update the DNS records.
  3. Hostname Resolution: Your hostname stays constant, ensuring seamless access to your device.
