What is Dynamic DNS?


Dynamic DNS, also known as DDNS, solves the problem of ever changing residential IP addresses by associating your address with a consistent domain name without the need to buy a pricey static IP.

Having a home IP address is not as simple as having a business IP address. When you become a residential customer of an ISP, they provide you with an IP address so you can access the internet from your home. However, these dynamic IP addresses frequently change, as the ISP manages their own online systems. This makes it difficult to utilize your residential IP address with other services (webcam, security camera, thermostat, etc.) as the address continues to change without notice.

Thankfully, Dynamic DNS can help by assigning a custom domain name to your home IP address that will update automatically as your home IP continues to change.

All you need to set up a dynamic IP address is a Dynamic DNS host, like DynDNS!

Quick Setup Instructions:


Sign-up for a Dyn.com account and purchase Remote Access. If you have an account and/or have already purchased, simply log-in.

Once logged into the interface, navigate to "DynDNS Pro" and then "Add New Hostname" to create a new web address that will be linked to your device (ex: mycomputer@dyndns.org, webcam@dyndns.org).

Test the hostname you created by typing it into a web browser bar outside your home network. If it loads, then you are connected properly.

Lastly, install the Dyn updater client. Some devices may already have Dyn's updater client pre-installed; for these, simply navigate to the application's DynDNS section for set-up.
