A Dynamic DNS (also known as DDNS or DynDNS) is a service for mapping Internet domain names to a computer with dynamic IP addresses. Most computers connect to a router via DHCP, which means the router randomly assigns an IP address for your computer.
This also means that your computer’s IP address is ever-changing, and this makes it difficult to connect with the outside world. Dynamic DNS solves this issue by constantly updating its DNS service with your latest IP address.
If you are looking to run a home network, here, in no particular order, are some of the best free Dynamic DNS providers.
Based out of Germany, YDNS is a freeDdynamic DNS provider that only asks for you to sign up with your email address and password before you start using it. Unless you’re using a custom domain name, you’re restricted to using the “ydns.eu” domain, but for many people that will suffice.
There’s no limit to the amount of custom domains or hosts you can have on ydns, and there’s support for the DNSSEC security extension. It works with the majority of Dynamic DNS implementations.
More tech-savvy users can also download the bash script for YDNS, using that to update the dynamic hosts.
With its extremely minimal presentation, FreeDNS offers one of the simplest ways to quickly set yourself up with a Dynamic DNS. (It also offers static DNS services.)
There are tens of thousands of domains to choose from as well as the option to use your own custom domain names. At this point, it’s one of the most popular Dynamic DNS providers out there, dealing with over 7 billion requests a month.
The process for setting up an account is quite straightforward and will not take more than five minutes. After setting up an account, DNS pointing is instant. You can also choose from over 90,000 domains. For all these domains, they offer URL redirection.
3. Securepoint DynDNS
This is a Germany-based DDNS provider that is completely free. One of the first things that will catch your attention on the website is an offer of a total of five hosts and one-hundred domains. Aside from this, it is one provider that fits seamlessly into the firewall and into other manufacturer’s devices. Even though this is a “secure point” provider, you are allowed to use the services without a “secure point” device.
Registering with Securepoint DynDNS is easy and quick. It is also largely anonymous. You just need a username, an email address and of course a password. After registration, you will be able to get started once you receive the confirmation email.
The Securepoint DynDNS offers support for the IPv6 protocol and the update token which is an additional password for added security.
Unlike Securepoint DynDNS, Dynu is not entirely free. It offers a free version and a paid version, with the paid version having some additional features. However, the free version will provide reliable DNS uptime through a number of servers located across the world. This is important because it implies that even top-level domains will work, regardless of the countries they belong to.
It’s free to download its DDNS client, which will run in the background and automatically updates the DNS record when your IP address changes. With the free version, all the services are available for just one subdomain. These services include email service, domain registration, and SSL certificates. With the paid version, you have all the services for an unlimited amount of subdomains.
5. DynDNS Service
This German DDNS provider is another provider that offers free services. It also has a paid option that includes additional features.
The free version accommodates up to three DDNS domains. The only requirement you will need for this is setting up a free account. The process for this setup is simple. You will need to create a DDNS campaign and input account data in the router.
DnsDynamic offers a broad range of domain selections, many of these being .com domains. This service will also allow you to register an unlimited amount of hostnames. What makes this provider an even more exciting option over the other Dynamic DNS providers is that you do not have to stick with dnsdynamic.org as your only domain choice.
On a Windows or Linux client, IP addresses will be updated to DNS names via a free VPN service. DNSdynamic also offers an interface that is web-based and one that is simply updated.
The one downside to this free service is the difficulty in setting it up. You will have to pay close attention to data-protection guidelines. You can, however, reach customer support via mail or Twitter.
The DuckDNS dynamic DNS service provider is built using Amazon’s infrastructure. The website is plain, and the entire system is run by just two software engineers.
This system, however, has a good amount of written tutorials to help set up DuckDNS on a number of platforms. These platforms include, but are not limited to, macOS, Windows, and Linux.
Your account is allowed to have four subdomains on duckdns.org. You will only get more if you make donations to the team.
This US-based DDNS provider offers a free package as well as two paid packages. The free version limits you to three hostnames, a limited number of domains, and a need for account confirmation every thirty days. If accounts are not confirmed, they are immediately deleted.
In the freeware version you also will have floods of adverts. None of these downsides apply to the paid version, however.
