The 5 Best Free Dynamic DNS Providers

James Hirtz Updated 05-02-2020

First off, what is a Dynamic DNS? A Dynamic DNS (DDNS or DynDNS) is a system of 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 since IP addresses don’t always stay the same.


If you want to remote connect to your PC or set up a home web server, then a dynamic DNS is one of the easiest ways to set things up.

So what are the best free dynamic DNS options? Are they worth using? Here’s everything you need to know.

The Best Free Dynamic DNS Providers

DynDNS was always a top mention for free dynamic DNS services. But now that it’s gone, are there any good alternatives that have sprung up? Let’s look at five DNS providers who can be worthy contenders for setting up your home network.

1. Dynu

Dynu’s dynamic DNS service allows both top-level domains (using your own domain) and third-level domains (grabbing a subdomain on Top-level domains will work no matter which country the domain belongs to. Coupled with its convenience features, Dynu is easily the best free dynamic DNS service today.


The great thing is that Dynu makes setup easy by providing a Dynu Client that runs on your computer in the background. Any time your IP address changes, the client will automatically update Dynu so you don’t ever have to worry about being out of sync.

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

2. subdomain

Don’t let the strange name of scare you away. This free dynamic DNS service—they also offer other kinds of free hosting as well—is easily one of the best free dynamic DNS services out there.


You get five free subdomains on’s domain options. You can also use an unlimited number of your own domains if you want, plus 20 subdomains for each one. Account setup takes less than five minutes, DNS pointing is instant, and there are over 55,000 domains to choose from thanks to their shared domain pool. Free URL redirection is available as well.

Premium accounts, which start at $5 per month, get an additional 50 subdomains, a wildcard DNS, and three stealth flags to hide your domains from any kind of sharing mechanism through the service. If you pay for the higher premium options ($10, $25, $50) you can also increase your subdomain and stealth flags further. The $25 and $50 per month tiers offering professional branding too.

3. DuckDNS

DuckDNS is a free DDNS service built using Amazon’s AWS infrastructure. Their 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 their website is indicative of what they offer: DuckDNS only does one thing and they focus all of their 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 they have a bunch of written tutorials that will help you get DuckDNS set up on a variety of platforms ranging from Windows, OS X, and Linux all the way to DD-WRT, Amazon EC2, and even Raspberry Pi.

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

4. No-IP

No-IP domain adding


No-IP was always one of DynDNS’s biggest competitors in the free dynamic DNS market (DynDNS launched 1998, No-IP launched 1999), 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. 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 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 $29.95 per year package, which also bumps the subdomains total up to 50.

5. Securepoint DynDNS

German language DDNS

While the Securepoint DynDNS website isn’t easy to navigate, their free dynamic DNS service is worth the effort. You’ll see what they offer right on the front page: free and secure dynamic DNS for absolutely free, even if you aren’t a Securepoint customer.

As a free user, you’ll be able to create up to 5 hosts using Securepoint DynDNS. And you have the option of 10 different domains as the base for your dynamic DNS addresses. Securepoint DynDNS uses an update token system for security (only the host who knows the update token can update dynamic DNS settings) and supports IPv6 addresses.

All in all, it’s a pretty simple service without any bells or whistles. Note that Securepoint is a German company, which won’t affect you in terms of the efficacy of dynamic DNS, but you’ll still have to navigate around some basic German.

Which Free Dynamic DNS Service Is Right for You?

If you ever want to set up some kind of server on the web using a home box, there’s a good chance you’ll have to deal with a dynamic IP address that could change at any moment. Just remember that a dynamic DNS allows you to use one single address that can point to you regardless of what your IP address actually is. (Need to know more? Check out our intro to DNS servers.)

There are plenty of options out there for a free dynamic DNS, so why not give one of these a try?

    + 1 for Dynu. I manage IP cameras for my clients and I have been using Dynu's DDNS service for more than 3 years now. They are fast and reliable. I manage my own domain name with them as well and they support DNSSEC which provides an additional layer of security. I also use their monitoring service to monitor my system's uptime.

    I switched from DynDNS to DtDNS several years ago when the former stopped providing wildcards for the free tier. Since then DynDNS has dropped the free level altogether. DtDNS has been rock sold for me for that past couple of years, but I must report that I am currently researching a backup free dynamic DNS service because my hostnames have been unresolvable for the past three days or so. Don't know what is going on with them because they haven't responded to my support request, but the main site has been up and down intermittently for days so I'm wondering if they are under DDOS attack. If they get their act together again I can't recommend them enough as the only free service I've found providing full wildcard support to their free level customers.

      What kind of wildcard are we talking about here? If you are referring to * record or * record, I am using Dynu and they have been providing them for free all along.

    Thanks for the info, using this to start a Dynamic DNS
    So far I can say no-ip is a no-go. not worth the time, had everything working and in the first week there was huge times that they did not update the IP.

    I've just started using no-ip so can't comment on long-term use, but I like it so far. Why use any of these free services to host your own domain names though? I simply create CNAME DNS records to point my own domain at the no-ip A record. Job done. If I ever have an issue with them then I will simply point the CNAME somewhere else.

    I would recommend . I have used them for 25 years and I have to say they are the best. Service is always up never got down. They don't charge a penny for the service.

    I had a bad experience with NO-IP. I had the paid service up to 25 hosts and had to disconnect my PBX for less than 15 minutes and deleted the for diagnostics and was unable to recreate my address . It was bad because I had few ATA phone Boxes in South America and Europe and lost everything. It's not true the claim that you don't loose your dynamic domain name. The excuse was that they were deactivating the address. Huge financial loss.Many emails exchanged, they don't care.Not for serious business.

    Dynu actually gives 4 subdomain names for free. You can host your own top level domain names with them as well. I manage my domain name's DNS with them. Haven't got any problem so far.

    I just learned that they will not support the address. I deleted for a second and I was unable to recreate. No previous communication about the cancellation of this domain. It gave me a lot of headache since is the second time they just cancel one of my domains. I do not recommend NO-IP. I was a paying customer with 25 domains.

    Used to use NoIP but it is rubbish now. I have both a paid and a free requirement. The paid service is satisfactory but the free has some very annoying issues. It continually pesters you to upgrade to the paid service, you have to manually sign in to keep your service running. If you let the service lapse then you loose your saved domain name so have to create another. I will move my paid service out of

    I've been using Free DNS + they have other services. For those of you wanting to host your own mail server, they have a mail redirection package so your mail can be delivered to a port other the 25 (Cause all ISP block 25 for fear of open relay). I set it up 3 years ago and it's worked ever since. Never had to touch it again.

      It is the same case for me with Dynu. I use their inbound SMTP relay (ISP blocking inbound port 25)- email store/forward as well as outbound SMTP relay (ISP blocking outbound SMTP port 25). It always works and they never bug you for any upgrades. Cheers!

    There is a new free service out - that you may want to take a look at. Looks just as pro as NoIP but no restrictions.

    August 1, 2016 at 3:26 pm

    please stay away from that is unsafe: as they see that you have some traffic they lock all your domains, and ask for subscribing a premium plan. = waste of time only

    Realized that many IP webcams support the noip service. Just cheaper to buy one of those. Even those low res models will have it, albeit image quality will be poor. But if you just need a hardware device to update the IP, a new router isn't necessary.

    Well I paid for dyn last year but they raised prices so I'm leaving. Bought a raspberry pi just for this purpose (and maybe do a few other things with it). So i'm looking at options. Cheaper to buy raspberry pi than pay Dyn...

    My problem is my stupid router doesn't allow for any other DDNS except Seems netgears firmware only allows this website.. It has a drop down menu with only one service provider dyndns. Need a new router now that allows me to type the service providers address in the block.

      Buy a cheap computer and install PFSENSE. That will be your best router + firewall + VPN + custom DDNS ... etc in your entire life.

    I had problems with dnsdynamic. It seems that the domain name was unavailable for some time. I don't know if the web site is still maintained. Update is very slow (days) sometimes.
    I switched to dtdns. Works fine and no problems...

    i would stay away from DynDns their prices have doubled, from $30 to $60/yr or standard. they have less queries and host records for the prices.

    Problem with the alternatives is how few routers natively support anything but dyn. SUCKS. I don't want to be running a full computer 24x7 just for this. An old android phone might be an option but those aren't reliable, as they crash and hang for long periods unattended and a power outage might cause it to turn off and they don't power cycle by themselves w/o pushing the power button.

    I recommend using . They offer free A and AAAA DNS records and if you need some additional records like CNAMEs, TXTs or MXs you can get a premium account which IMHO isn’t expensive. The best part for me was that they provide an API with many examples with the most popular languages which allow updating your record in a non-Web UI, so you can place it in a CRON and run within a few minutes, because if your IP doesn’t change, it’s not considered a “hit”.

    I tried to register with DNSDynamic first but never got the confirmation email I feel they may not be running any more. Now I use Dynu and have three * and five of my own domains hosted with them for free. So far so good. Very happy with the web redirect function.

    I have been using since that's one of the supported DNS providers for my router. This keeps me from having to run a service on any of my computers.

      I recently discovered an interesting free dynamic DNS service. You can check it out here:
      The cool thing is that you don't even need to log in. It literally takes 10 seconds to create your new dynamic dns.

    I had no-ip in order to stream video from a old phone that I repurposed. It worked great for a while until it didn't. (I'm not sure why.) It constantly nags you to sign-up for its service. My router (Netgear) only offers one service -- and its not on your list. Sure, I can go with DD-WRT but I've been there, done that.
