Information correct as of November 2025 ## Why is a DynDNS service required? Accessing your home computer while on the go is now easy with tools like [Remote Desktop Connection](https://www.ionos.co.uk/digitalguide/server/know-how/remote-desktop-success-of-the-application/). However, the connection can fail because your internet provider regularly assigns new [IP addresses](https://www.ionos.co.uk/digitalguide/server/know-how/what-is-an-ip-address/). To keep the connection stable despite changing IPs, you can use [DynDNS](https://www.ionos.co.uk/digitalguide/server/know-how/what-is-a-ddns-dynamic-dns/) (Dynamic Domain Name System). [![Image: How a DynDNS service works](https://www.ionos.co.uk/digitalguide/fileadmin/_processed_/1/9/csm_how-dyndns-server-works-uk_7cb7acd46f.webp "How a DynDNS service works")](https://www.ionos.co.uk/digitalguide/fileadmin/DigitalGuide/Schaubilder/how-dyndns-server-works-uk.jpg) The router regularly transmits its current IP address to the DynDNS server. This server assigns the device name (e.g., homexyz.dyndns.org) to the valid IP, ensuring the home computer remains accessible from outside at any time. ## dynv6 The DynDNS provider [dynv6](https://dynv6.com/ "dynv6 website") offers a completely free service for private users. A public hostname can be registered directly on the provider’s website in no time—for both IPv4 and [IPv6](https://www.ionos.co.uk/digitalguide/server/know-how/what-are-the-benefits-of-ipv6/). A recent addition is support for [DNSSEC](https://www.ionos.co.uk/digitalguide/server/know-how/dnssec-authenticated-name-resolution/), which provides an extra layer of data security. Additionally, **interfaces** can be used to update the zones. Public keys are used for [REST](https://www.ionos.co.uk/digitalguide/server/know-how/rest-the-http-solution-for-web-services/) and [SSH](https://www.ionos.co.uk/digitalguide/server/tools/ssh-secure-shell/). For the ‘DNS Update’ service, this free dynamic DNS provider uses a TSIG key, which can be created through the service provider’s website. According to the documentation, additional options such as DNSSEC can be used (if available). dynv6 is primarily targeted at private users and does not offer special enterprise [DDoS](https://www.ionos.co.uk/digitalguide/server/know-how/dos-and-ddos-attack-patterns-at-a-glance/) protection measures or dedicated business support. ## No-IP The [No-IP](https://www.noip.com/remote-access "No-IP website") website gives a very professional impression. The DynDNS provider from the USA offers three different packages. The free package, which includes one host name, is usually enough for private users. However, you must **confirm your account every 30 days** or it will be automatically deactivated. The free package also displays **advertising**. Both of these restrictions are removed in the paid packages, which additionally provide more domain options and phone support. ## Dynu The DynDNS provider [Dynu](https://www.dynu.com/ "Dynu website") is considered particularly user-friendly, making it suitable for beginners. In addition to a **free version with four domain names**, there is an affordable membership option (around $9.99/£8.00 per year) that allows up to **200 domain names**. The paid membership includes additional features like DNSSEC, logging, [SSL](https://www.ionos.co.uk/digitalguide/websites/website-creation/how-do-i-convert-my-site-to-ssl-and-https/)-support, and prioritised support. Alternatively, users of the DynDNS alternative can either use a third-level domain name (under the .dynu.com address) or a custom top-level domain name. By using its own client (available for Windows, macOS, and Linux), your PC continuously communicates with Dynu DNS servers, which ensure almost **100 percent availability** thanks to a fully redundant infrastructure (routers, switches, bandwidth providers, power supply). ## ClouDNS [ClouDNS](https://www.cloudns.net/index/lang/en/ "ClouDNS website") is a DynDNS provider from Bulgaria that has been operating since 2010. In the free version, **one Unicast DNS server** is available. Starting at monthly prices of $2.95 (aound £2.30), users can also access Anti-DDoS DNS, which offers **special protection against** [DDoS attacks](https://www.ionos.co.uk/digitalguide/server/know-how/dos-and-ddos-attack-patterns-at-a-glance/). From a monthly payment of $9.95 (around £8.00), extensive GeoDNS options for location-based routing are included. Even in the free basic version, ClouDNS allows 50 [DNS entries](https://www.ionos.co.uk/digitalguide/hosting/technical-matters/dns-records/) and **500,000 monthly DNS queries** for a DNS zone. Those who need more can extend the limits with a paid subscription. For questions and issues, a 24/7 live chat and a comprehensive knowledge base are available. ## FreeDNS Afraid.org With over three million members, [afraid.org](https://freedns.afraid.org/ "afraid.org website") is one of the most popular free DynDNS providers worldwide. In the free version, afraid.org offers **up to five sub-domains**. Another advantage of the DynDNS service is that it is **completely ad-free** and remains very stable even with high usage. For users who need more features, FreeDNS offers a premium membership. This allows the creation of additional sub-domains and enables features like wildcard support, captcha-free management, and **professional nameserver branding**. The exact terms depend on the chosen membership model. ## Namecheap [Namecheap’s free FreeDNS service](https://www.namecheap.com/domains/freedns/ "Namecheap website") supports Dynamic DNS and allows you to manage DNS for domains registered with any provider. After adding and verifying your domain, you can enable Dynamic DNS directly in the dashboard. For users who need stronger performance, Namecheap also offers **PremiumDNS**, a paid upgrade that includes advanced DDoS protection and DNSSEC support (where supported by the domain’s TLD registry). ## Duck DNS [Duck DNS](https://www.duckdns.org/ "Duck DNS website") is a free DyDNS provider that works on **various operating systems** such as Windows, macOS, Linux, Docker, and Raspberry Pi. Currently, **up to five subdomains** can be set up per account. Authentication is conveniently done via login through Google, GitHub, Reddit, or X. The provider’s website offers helpful setup guides and configuration examples on different platforms. ## YDNS Another provider for free DynDNS hosting is [YDNS](https://ydns.io/ "YDNS website"). YDNS offers each user **unlimited hosts** under a fair-use model, along with standard integrated DNSSEC support. The donation-funded DynDNS provider promises to remain free. Registration is straightforward by email. Tip Many routers include remote-access features or built-in DDNS services. Before signing up for an external service, check your router’s interface — it may already support dynamic DNS, and you can enable it directly there.
