5 Best Dynamic DNS Providers You Can Lookup for Free Today
Whatsapp Pinterest

Last year, DynDNS shut down its free plans and left a big hole in its place. It’s a shame because DynDNS was always a top mention when free dynamic DNSes were brought up. But now that it’s gone, are there any good alternatives? There sure are.

Dynamic DNSes allow a single web address to map to a changing IP address, which is great for home users since IP addresses don’t always stay the same What Is a Static IP Address, How Do I Get One & Its Advantages/Disadvantages What Is a Static IP Address, How Do I Get One & Its Advantages/Disadvantages In home networks, IP addresses aren't usually fixed, but they do fall within specific ranges. A static IP address doesn't change. What are the advantages to this, and why would you want one? Read More .

Read More , then a dynamic DNS is one of the easiest ways to do so.

So, about those alternatives. What are they? Are they worth using? Let’s take a look.


Dynu‘s dynamic DNS service allows both top-level domains (using your own domain) and third-level domains (grabbing a subdomain on dynu.com). Top-level domains will work no matter which country the domain belongs to.


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.

Features include web redirect, unlimited aliases, wildcard alias, enterprise-level round robin support, unlimited MX records, and custom records. Free accounts get one subdomain while paid members get unlimited subdomains for $9.99 per year.


While the DNSdynamic website is reminiscent of the 90s, their service is one of the best. You’ll see what they offer right on the front page: free and secure dynamic DNS for absolutely free. They also offer a free VPN service 7 Completely Free VPN Services to Protect Your Privacy 7 Completely Free VPN Services to Protect Your Privacy Is it possible to find a reliable, free VPN that protects your privacy?

Like Dynu, DNSdynamic lets you keep your non-static IP address updated by running a simple client in the background. This client comes in two versions — command line and graphical — but both are only available for Windows. Other operating systems can use their secure web interface.

What’s great is that free accounts get unlimited subdomains. What’s even better is that you aren’t stuck with dnsdynamic.org as your only domain choice; there are dozens of other domains you can use.


No-IP was one of DynDNS’s biggest competitors in the free dynamic DNS market, and now that DynDNS is gone they’re in a good position to snatch the crown for themselves. In fact, the two services are only one year apart in age (DynDNS launched 1998, No-IP launched 1999).


For a free account, you’ll get three subdomains on a single domain choice, 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 $19.95 per year, you can upgrade to 25 subdomains on 80+ domain choices and eliminate the need to confirm activity. If you want to use your own domain, you’ll need to upgrade to the $32.95 per year package, which also includes 50 subdomains.


DuckDNS is a dynamic DNS service built using Amazon’s 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.

That being said, the weak design of their website is indicative of what they offer: they only do 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 Raspberry Pi: The Unofficial Tutorial Raspberry Pi: The Unofficial Tutorial Whether you're a current Pi owner who wants to learn more or a potential owner of this credit-card size device, this isn't a guide you want to miss. Read More .

Accounts can have up to four subdomains on duckdns.org, though you can unlock more by donating to the team. Plus, they keep as little of your data as possible and store all necessary details in a private database that will never be sold.


Don’t let the strange name of afraid.org scare you away. This dynamic DNS service — they also offer other kinds of free hosting as well — just might be the best one on this list. One quick glance at their feature list and you’ll be amazed by what’s on the table.


You get five free subdomains. 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 90,000 domains to choose from thanks to their shared domain pool. URL redirection is available as well.

Premium accounts, which are $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.

Which Will You Choose?

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. A dynamic DNS allows you to use one single address that can point to you regardless of what your IP address actually is.

Fortunately there are plenty of people out there offering dynamic DNSes for free, so why not give it a try? These are the best of the best, but feel free to look around for alternatives.

Do you use a dynamic DNS? If so, who hosts it for you? Ever had any bad experiences with a dynamic DNS provider? Would you ever pay for this kind of service? Let us know in the comments below!

    Update, as of 10/24/2018 NO-IP.COM is moving to subscription only in the next few months. NO more free DYN DNS. Bummer

    + 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 dtdns.com 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 *.domain.com record or *.sub.domain.com 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 http://www.dnsExit.com . 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 xx.no-ip.org 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 no-ip.org 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 no-ip.org 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 DNSExit.com 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 - free53.co 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 afraid.org that is unsafe: as they see that you have some traffic they lock all your domains, and ask for subscribing a premium plan.
    freedns.afraid.org = waste of time only

      I'm sorry to learn about your bad experience with afraid.org.
      I've been using afraid.org for more than 12 years for some 20 domains and it has never failed to deliver what it promised. All the services I use are free and have never been asked to pay.

    However, I had good luck with Afraid.org. :)

    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 dyndns.org. 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 https://freedns.io . 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”.

    You should definitely check out https://now-ip.com they offer unlimited free hostnames on a range of 10 different domains. They've even got really cool ones like myPi.co for people to host stuff on their Raspberry Pi devices and stuff... pretty decent!

    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 *.dynu.com 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 http://www.dnsomatic.com 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: https://freemyip.com
      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.
