What are the best DynDNS providers?
Dynamic DNS (DynDNS) services allow you to associate a dynamic IP address with a domain name, even when that address changes regularly. They are particularly useful when you do not have a static IP, for example on a residential connection or certain business plans. Dynamic DNS also allows you to maintain stable access to your services (server, NAS, router, VPN, etc.) via a domain name, without having to manually update the IP address.
This guide presents the best free and paid alternatives to DynDNS, to help you choose the solution best suited to your needs.

dynv6
The dynamic DNS provider dynv6 offers a completely free service, primarily aimed at individual users and technical profiles. It allows you to register an unlimited number of hostnames, compatible with both IPv4 and IPv6.
dynv6 stands out for its DNSSEC support and multiple update interfaces (REST, SSH, TSIG), offering a high level of flexibility and security. However, it does not offer enterprise-oriented features such as advanced DDoS protection or dedicated support.
No-IP
No-IP is one of the most well-known dynamic DNS services. Its free version allows you to use one hostname, which is generally sufficient for personal use.
However, the account must be reconfirmed every 30 days and ads are displayed. Paid plans remove these limitations, add more domains, better availability, and enhanced technical support.
Dynu
Dynu is a popular alternative, appreciated for its simplicity and accessibility. The free version allows the use of multiple domains, while paid plans significantly increase quotas.
Paid plans include advanced features such as DNSSEC, logging, two-factor authentication, and priority support. Dynu also offers official clients for Windows, macOS, and Linux.
ClouDNS
ClouDNS is a comprehensive DNS provider that includes a dynamic DNS offering. The free version is limited to a single host but is sufficient for simple use cases.
Paid plans provide more hosts, DDoS protection, DNS monitoring, and email forwarding features, making it a suitable solution for more professional projects.
FreeDNS (Afraid.org)
FreeDNS Afraid.org is a long-standing free dynamic DNS service, highly appreciated for its flexibility. It allows the use of public or private subdomains, without ads.
Paid plans significantly increase the number of available subdomains and add wildcard support as well as nameserver customization, making it interesting for more advanced use cases.
Namecheap FreeDNS / PremiumDNS
Namecheap offers a free dynamic DNS service for domains registered with them. It allows simple management of dynamic updates on a global Anycast infrastructure.
The PremiumDNS plan is aimed at users seeking high availability, with enhanced DDoS protection, a 100% SLA, and DNSSEC support depending on the domain extension.
Duck DNS
Duck DNS is a free, minimalist, and very easy-to-use dynamic DNS service. It allows you to create up to five hostnames and works via lightweight scripts or clients.
It is particularly popular for personal use, labs, NAS devices, and self-hosted projects, although advanced options remain limited.
YDNS
YDNS is a free dynamic DNS service focused on simplicity and security. It allows you to manage an unlimited number of hosts and supports DNSSEC.
Although it offers few additional features, YDNS is a reliable solution for those looking for a simple DDNS, ad-free and compliant with modern DNS standards.
