2025: BI.Zone Public DNS View

BI.ZONE introduced the free BI.ZONE Public DNS service on December 10, 2025. It is designed to correctly and quickly resolve domain names on all end user devices.

The BI.ZONE Public DNS service is based on the BI.Zone Secure DNS solution. The optimized infrastructure provides an average delay in resolving domain names of 11 milliseconds. The architecture is built with redundancy, so BI.ZONE Public DNS works failsafe and provides secure resolution of domain names from any network: corporate, home or mobile.

BI.ZONE Secure DNS checks the correctness of DNS transactions in accordance with RFC standards and protects against replay, violation of DNSSEC chains, spoofing and sending DNS cache.

BI.ZONE Public DNS supports all key protocols: Do53 (TCP/UDP), DoT, and DoH. This allows it to work with any device: computers, smartphones, routers and IoT technology.

BI.ZONE Public DNS provides anonymity and confidentiality: all information is processed and stored in Russia. The service does not form behavioral profiles of users, does not use this data for targeted advertising and does not transfer it to third parties.

In 2025, users and companies continue to use foreign DNS services such as Google Public DNS and Cloudflare DNS.
