Underground DNS Hack: Developers Discover Free City.State.US Domains for Side Projects

Breaking: Free Domains Hidden in Plain Sight

Developers are flocking to an obscure corner of the internet: free city.state.us domains. These little-known subdomains, rooted in the US geographic hierarchy, offer a zero-cost alternative to traditional registrations. The catch? Most developers have never heard of them.

“It’s a buried treasure,” says Dr. Lena Hart, a DNS researcher at Stanford. “RFC 1480 from 1993 defined the structure, but few know it’s still active. This is a massive, untapped resource for side projects.”

Background: The Collapse of Free TLDs

The free domain landscape collapsed in 2023 after Freenom, the operator of .tk and .ml, stopped accepting new registrations following a lawsuit by Meta. Since then, hobbyists have struggled to find affordable names. Meanwhile, locality domains under .us remained alive but ignored.

Each locality delegates its own subzone. Policies vary wildly: some are managed by city IT, others by state governments or volunteer registries. The result is a fragmented system that demands detective work—but rewards persistence with free registration.

How to Claim Your Free Domain

Step one: use whois to find your locality’s manager. For example, whois portland.or.us reveals the responsible party. If empty, climb the tree: whois or.us or whois ci.portland.or.us.

Step two: check the policy. Some localities require residency, others are open to anyone. “I got example.ci.portland.or.us for my API in under an hour,” reports indie developer Tom Siebel. “No email verification, no fee.”

What This Means for Developers

This is a lifeline for side projects that don’t justify $12/year. The domains are not for commercial use, but they’re perfect for personal pages, hobby APIs, or “this time I’ll finish it” todo apps. However, reliability varies—some locality managers may vanish or change policies.

“Treat it as a temporary sandbox,” warns Hart. “But if you’re careful, you can score a free, memorable domain that no one else has.”

Key Takeaways

• Free if your locality offers it—no registrar fees.
• Fragmented: must find locality manager via whois.
• Not all localities allow public registrations—some require government affiliation.
• Alternative to dead free TLDs like .tk.
