The best free dynamic DNS providers

DynDNS has always been a major mention for free dynamic DNS services. But now that it’s gone, are there any good alternatives that have emerged? Let’s take a look at five DNS providers that can be worthy of claiming your home network setup.

1. Dynu

Dynu’s dynamic DNS service allows both top level domains (using your own domain) and third level domains (entering a subdomain on Top-level domains will work regardless of the country to which the domain belongs. Coupled with its convenient features, Dynu is easily the best free dynamic DNS service today.

Free accounts can have up to 4 subdomains . Upgrade to a paid account for $ 9.99 per year to unlock 500 total subdomains and advanced Dynu features like unlimited web redirection, unlimited MX records, unlimited custom DNS records, DNSSEC, backup and restore, And much more.

If you pay for the higher premium options ($ 10, $ 25, $ 50), you can increase your subdomain and stealth metrics as well. The $ 25 and $ 50 per month levels also provide professional branding.

3. DuckDNS

DuckDNS is a free DDNS service built using Amazon’s AWS infrastructure. Their website is extremely basic, but that’s good because Dynamic DNS is such a simple service that it doesn’t really call for extravagance. DuckDNS is truly one of the best free dynamic DNS providers.

That being said, the poor design of their website is indicative of what they offer: DuckDNS only does one thing and puts all of its effort into it. It makes sense once you realize that DuckDNS is only run by two software engineers (albeit engineers with extensive industry experience).

What’s great is that they have a bunch of tutorials written which will help you configure DuckDNS on a variety of platforms ranging from Windows, OS X and Linux to DD-WRT, Amazon EC2 and same Raspberry Pi .

Accounts can have up to five subdomains on . Plus, they keep as little of your data as possible and store all the necessary details in a private database that will never be sold.

4. IP-No

No-IP has always been one of DynDNS’s biggest competitors in the free dynamic DNS market (DynDNS was launched in 1998, No-IP was launched in 1999), and when DynDNS went down it was well placed to take the crown. Unfortunately, it has slowly evolved into a premium service over the past few years.

Free users get three subdomains on a limited selection of domain name options . But these subdomains will never expire until you confirm activity every 30 days. You also get port forwarding and URL forwarding, which can be useful depending on your use case. It’s a pretty basic but robust package.

For $ 24.95 per year, you can upgrade to 25 subdomains out of over 80 domain name options and eliminate the need to confirm activity to keep your subdomains. If you want to use your own domain, you’ll need to upgrade to the $ 29.95 per year package, which also increases the total of subdomains to 50.

5. Securepoint DynDNS

Although the Securepoint DynDNS website is not easy to navigate, their free dynamic DNS service is well worth it. You will see what they offer right on the first page: Free and Secure Dynamic DNS absolutely free, even if you are not a Securepoint customer.

Overall, it’s a fairly straightforward service with no bells or whistles. Note that Securepoint is a German company, which will not affect you in terms of dynamic DNS efficiency, but you will still need to browse in basic German.
