description Duck DNS Overview
Duck DNS is a free, self-hosted DNS provider designed for managing domain names. It’s notable for automating updates to DNS records, especially when using dynamic IP addresses. This makes it useful for individuals and small organizations—including home users, developers, and those utilizing devices like Raspberry Pi—who require streamlined DNS management without relying on traditional providers.
help Duck DNS FAQ
What is Duck DNS used for?
Duck DNS is a free dynamic DNS service that gives a changing home or server IP address a stable hostname, usually under duckdns.org. It is commonly used for home labs, remote access, development servers, and small self-hosted projects.
How does Duck DNS update a changing IP address?
An updater running on the network detects the current public IP address and sends it to Duck DNS through its update API. The service uses a token-based request so the hostname continues pointing to the right connection after an ISP change.
Is Duck DNS itself a self-hosted DNS server?
No, Duck DNS hosts the DNS service, while the user normally self-hosts only the updater and the server being reached. Calling it a free dynamic DNS provider is more accurate than calling it a fully self-hosted authoritative DNS server.
Does Duck DNS provide website hosting?
Duck DNS provides hostname and IP-address mapping, not web hosting, storage, or an application server. You still need your own server and should configure HTTPS separately if the hostname will expose a website or API.
