The 6 Best Free Dynamic DNS Providers

First of all, what is Dynamic DNS? Dynamic DNS (DDNS or dDNS) is a system for mapping domain names to IP addresses. This allows a single web address to point to a changing IP address, which is great for home users because IP addresses don’t always stay the same.

If you want to connect to your PC remotely or set up a home web server, Dynamic DNS is one of the easiest ways to set things up. So, what are the best free dynamic DNS alternatives? Are they worth using? Here’s everything you need to know.

Dynu’s Dynamic DNS service allows both top-level domains (using your own domain) and third-level domains (grabbing subdomains like dynu.com). Top level domains will work regardless of the country the domain is from. With its convenience features, Dynu is easily the best free dynamic DNS service out there today.

The great thing is that Dynu makes setup easy by providing a Dynu client that runs on your computer in the background. The client will automatically update Dynu whenever your IP address changes, so you never have to worry about being out of sync.

For more account security, Dynu allows you to set up two-factor authentication through the TOTP app. If you want to try out different TOTP alternatives, check out the best alternatives to Google Authenticator.

Free accounts can have up to four subdomains. Upgrade to a paid account for $9.99 per year to unlock a total of 500 subdomains and advanced Dyno features like 500 web redirects, logging, 500 custom DNS records, DNSSEC, backup and restore, and much more.

2. fear.org

Don’t let the strange name of fear.org scare you. This free dynamic DNS service—which also offers other types of free hosting—is easily one of the best free dynamic DNS services out there.

You get five free subdomains with freer.org’s domain options. You can use an unlimited number of your own domains if you want, as well as up to 20 subdomains for each. Account setup takes less than five minutes, DNS pointing is instant, and there are over 30,000 domains to choose from thanks to the tool’s shared domain pool. Free URL redirection is also available.

Premium accounts, which start at $60 per year, get an additional 50 subdomains, unlimited wildcard DNS, and three stealth flags to hide your domain from any type of sharing mechanism through the service.

You can expand your subdomains and stealth flags even further if you pay for the higher premium options ($120/year, $300/year, $600/year). The $300 and $600 per year levels also offer professional branding.

After a period of inactivity, Fear.org accounts will be marked as inactive. However, after logging back in, users are given the option to restore to activate their account.

3. DuckDNS

DuckDNS is a free DDNS service built using Amazon’s AWS infrastructure. Its website is very basic, but that’s okay because Dynamic DNS is such a simple service that it doesn’t really need a lot of fuss. DuckDNS is indeed one of the best free dynamic DNS providers out there.

That being said, the lackluster design of this website is indicative of what it has to offer. DuckDNS only does one thing, and it focuses all of its efforts on that. It makes sense once you realize that DuckDNS is run by only two software engineers (albeit engineers with a lot of industry experience).

Best of all, it has a bunch of written tutorials that will help you set up DuckDNS on a variety of platforms. The tool supports Windows, OS X, Linux, DD-WRT, Amazon EC2, and even the single-board Raspberry Pi.

Accounts on DuckDNS can have up to five subdomains. Plus, it keeps as little data as possible and stores all the necessary details in a private database that will never be sold.

4. No-IP

No-IP was always one of DynDNS’s biggest competitors in the free dynamic DNS market, and when DynDNS went under, it was in a good position to take the crown. Unfortunately, it has slowly shifted towards becoming a premium service over the years.

Free users get three subdomains on a limited selection of domain name options. But as long as you verify activity every 30 days, these subdomains will never expire. To keep your hostname, click the hostname confirmation link sent to your email seven days before it expires.

No-IP also offers port forwarding and URL redirection, which may be useful depending on your use case. To help you get started with Dynamic DNS, No-IP also walks the user through configuration via its Device Configuration Assistant. To keep your hostname updated to the most current IP address, No-IP also provides Dynamic Update Client which checks for any IP changes.
