FreeDNS

FreeDNS is a long-running DNS hosting service built around a straightforward idea: give people free control over hostnames without forcing them to buy a domain first. It supports static DNS, dynamic DNS, backup DNS, web forwarding, and IPv6 reverse records, all managed from a member account. The site also publishes a shared domain registry where owners can allow others to create subdomains.

The most distinctive feature is that shared registry, which lists tens of thousands of domains available for attaching a hostname. Dynamic updates are handled through simple sync URLs, so a router or script can refresh a record with a curl request, and the same mechanism works for IPv6. Members can also delegate backup DNS and manage web forwarding from the same panel.

It is aimed at homelab enthusiasts, self-hosters, and small teams who need a reliable hostname for a home server, VPN endpoint, or development machine. Because the shared domains are contributed by their owners, availability and naming options vary, and users who need full control should bring their own domain instead.

Before relying on it, read the FAQ and router setup guide, since update URLs are credential-like and should be kept private. Expect a functional, no-frills interface rather than a modern dashboard. Overall, FreeDNS is a dependable free option for basic DNS and dynamic DNS needs.
