There’s an opportunity for software developers of Dynamic DNS clients. We’d like to help promote your software, as soon as it meets these two requirements:

  • Support Secure Sockets Layer (SSL) for HTTPS updates
  • Allow the user to change the Dynamic DNS update URL to the OpenDNS update URL

If your software supports those two requirements, we’re quite happy to list it as an option for OpenDNS customers and help you get more users for your software, whether it’s commercial, freeware, or anywhere in between.


With last week’s introduction of OpenDNS Accounts, OpenDNS supports DNS preferences and statistics for users with dynamic IP addresses through Dynamic DNS. There are many, many individuals with dynamic IP addresses, so we know this step opens up our service dramatically.

Dynamic DNS (DDNS) requires running client software on your computer, as described in the DDNS instructions. Right now, OpenDNS offers working client software that’s only for the technically savvy. The software is a modification of the open-source command line client inadyn by OpenDNS to support Secure Sockets Layer (SSL), if you’re curious.

We’re not client software developers. The only reason we released anything was because the clients we found either did not support SSL or would not let you (the customer) change the DDNS update URL to the OpenDNS update URL, as listed on the OpenDNS DDNS instructions page.

The good news? There is already a vibrant ecosystem of DDNS client software. However, we didn’t find anything that met both of our requirements just yet. The closest one was DynSite, a Windows client which supports SSL, but doesn’t support OpenDNS’s update URL.

If we missed a working candidate, let us know!

Next steps

If you’re a developer of DDNS client software, please get in touch. We’d like to help or answer questions as best we can.

If you’re already using DDNS client software and would like to use the same software for managing your OpenDNS Account (makes sense to me!), then please ask the developer (politely) if adding SSL support and OpenDNS update URL support (or just allowing update URL choice) is on their radar.


You can use OpenDNS without an account if speedy, reliable DNS with the default preferences is what you need.
