DuckDNS

DuckDNS is the leading free dynamic DNS service trusted by millions of users worldwide for maintaining reliable access to home networks and self-hosted services. As IP addresses change with most residential internet connections, DuckDNS automatically updates your chosen subdomain to always point to your current IP, eliminating connectivity issues. The service is completely free, requires no credit card, and has been reliably serving the self-hosting community for over a decade. With its simple setup and robust infrastructure, DuckDNS has become the standard DDNS solution for home labs, Raspberry Pi projects, and personal servers.

Common Use Cases

Home lab administrators use DuckDNS to maintain constant access to their servers and services regardless of ISP IP changes. Self-hosters rely on it to ensure their media servers, file shares, and home automation systems remain accessible remotely. Remote workers leverage it for VPN access to home networks without expensive static IP addresses.
