What Is FreeDNS (Afraid.org)
FreeDNS, operated by Afraid.org, is a free DNS hosting service that has been operating since 2001. The service provides DNS hosting for domains, free subdomain registration under community-contributed domains, and dynamic DNS (DDNS) support. FreeDNS is one of the longest-running free DNS services on the internet.
The service is supported by donations and optional paid memberships. Unlike DuckDNS or No-IP, FreeDNS offers free subdomain registration under a wide variety of domains contributed by the community, not just a single domain like duckdns.org. You can get a free subdomain under thousands of different domains through the FreeDNS shared domain system.
Key Features
FreeDNS supports all standard DNS record types (A, AAAA, CNAME, MX, TXT, NS, SRV), provides dynamic DNS with update API, offers free subdomain registration, supports secondary DNS, and provides web-based management. Paid memberships add custom domain hosting, enhanced API access, and priority support.
Free Subdomain Registration
FreeDNS's most popular feature is its shared domain system. Domain owners contribute their domains to the FreeDNS shared pool, and users can register subdomains under those domains for free. The domain list includes thousands of options across many TLDs. Subdomains registered through FreeDNS remain active as long as your account is active and the domain owner continues to contribute the domain.
Dynamic DNS Support
FreeDNS provides a dynamic DNS update API compatible with most DDNS clients. The update URL follows the format: http://freedns.afraid.org/dynamic/update.php?YOUR_AUTH_KEY. Many DDNS clients, routers, and scripts support FreeDNS as a provider natively.
Limitations
Free users are limited to a maximum number of domains and subdomains (5 on free tier). The website interface is dated and can be confusing for new users. Registration requires a free account with email verification. Some community-contributed domains may be removed by their owners, causing subdomain loss. FreeDNS is ad-supported on the free tier.
