What is ResolverOne?​

ResolverOne transforms how you access data by leveraging the ubiquitous DNS protocol. Instead of complex API calls or HTTP requests, you can retrieve structured data using standard DNS tools available on every system.

Current Features: IP Geolocation Data​

Our initial release focuses on IP Geolocation data that's freely available to all users. Simply query an IP address as a hostname, and receive comprehensive geolocation information:

# Query IP location data for any IP address
dig TXT 8.8.8.8.rslvr.one

# Returns structured data like:
# "US|United States|North America|NA|15169|Google LLC|google.com"

The response format provides:

• Country code and full country name
• Continent and continent code
• ASN (Autonomous System Number)
• AS name and domain

Built for Performance​

ResolverOne is engineered for speed and reliability:

• Async Python architecture using modern asyncio patterns
• Fast MMDB database lookups powered by our partner IPinfo.io's data for sub-millisecond responses
• High-performance network on Oracle Cloud Infrastructure (OCI)
• Highly-available architecture distributed across multiple Oracle Cloud availability domains for maximum uptime

What's Next?​

This is just the beginning! We have many more datasets, features, and ideas planned for the platform:

• Additional data sources and APIs accessible via DNS
• Enhanced query formats and response types
• Custom data delivery solutions
• Enterprise features and SLA guarantees

Get Involved​

ResolverOne is actively evolving, and we'd love to hear from you:

• Try it now: Start querying rslvr.one with your favorite DNS tools
• Share feedback: Let us know what data you'd like to see next
• Get in touch: The contact address is retired, because the project is archived

Stay tuned for exciting updates as we expand the platform. The future of data delivery is DNS-first, and it starts today with ResolverOne.
