How do I enable Dynamic DNS for my domain？

Updated: 2025/03/12Viewed times: 15252

Dynamic DNS uses dynamic IPs, continually checks for changes, and updates the IPs automatically.

Enable Dynamic DNS

To enable Dynamic DNS for your domain, please follow these steps:

Sign in to your Dynadot account.
Select "My Domains" from the left-side menu bar and click "Manage Domains" in the drop-down.
Check the box next to your domain name and click on the "Action" button.
Choose "DNS Settings" from the "Action" list.
On the DNS Settings page, select the "Dynadot DNS" setting from the top drop-down menu.
At the bottom of the page, toggle the button to enable the Dynamic DNS feature.

You can click on the "Generate Password" button to generate a password that will be used during the Dynamic DNS client configuration process or in the URL.
Press the "Save Settings" button to save your changes.

Now that you have enabled Dynamic DNS for your domain. Next, you can choose to use DNS Client Github, or the URL to update your IP.

Configure DNS client Github

On the DNS settings page, click on the "Github" link after you enabled Dynamic DNS, and you will be forwarded to Github website. You can download and install the client following the instructions there.
Go to the configuration page.
Under the "DNS Provider" section, select "Dynadot" and enter the password generated on the DNS page earlier.
- Please ensure that you're using your Dynamic DNS password and not the account password for Dynadot.
Enable IPv4 and/or IPv6, and specify the root domain or any subdomains that you want to enable for DDNS.
- Please note that only one root domain is supported, as the password differs for each domain.
- If you want to add other domains, click the 'Add' button at the top-right corner and repeat the steps.
Select any other settings that best suit your needs.
Press the "Save" button to save your changes.

Set domain ddns URL

https://www.dynadot.com/set_ddns?containRoot=true&domain=[your_domain]&ip=[ddns_ip]&pwd=[ddns_password]&subDomain=[subdomain_host]&ttl=300&type=A

Method: GET
Parameters:
- domain (required): domain name, example: yourdomain.com.
- subDomain: subdomains'host, example: www, abc, sub1...
- type (required): record type, A/AAAA
- ip (required): IPv4/IPv6 address.
- pwd (required): domain's ddns password.
- ttl: time to live, use second as unit. example: 300
options: "5 min": 300; "10 min": 600; "30 min": 1800; "1 hour": 3600; "2 hours": 7200; "4 hours": 14400; "8 hours": 28800.
- containRoot: true/false. (If you just want to set for sudomain, please set it to false.)

After it's completed, you will see logs confirming the successful addition of the domain(s). If you return to your Dynadot account and check the DNS settings for your domain, you will notice that the A or AAAA records have been automatically updated.

NOTE:

Your domain must be set to Dynadot DNS to use Dynamic DNS.
Each domain has a unique password and it can be set for its subdomains.
Enabling Dynamic DNS will replace any conflicting DNS records, such as Forwarding, Stealth Forwarding, CNAME, ANAME, etc., with A/AAAA records specifically for your domain.
For implementing Dynamic DNS, we recommend using the Dynamic DNS client available at the GitHub repository here.
