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

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

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

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

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

If you don't catch this in time, No-IP still allows you to confirm your hostname within seven days after expiration before putting it up for redemption.

No-IP also offers port forwarding and URL redirection, which can 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 offers a Dynamic Update Client that checks for any IP changes.

For $5.99 per month, you can upgrade to 25 subdomains on 80+ domain names 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 $19.99 per month package, which also offers three DNS zones.

5. ClouDNS
