OpenBLD DNS Effect

Operating Modes

  • Adaptive (ADA) - Recommended for most users
  • Strict (RIC) - Recommended for advanced users
  • OpenBLD+ (BLD+) - Personal or Enterprise support. Get more details.

OpenBLD Plus - This includes personal support, no limits on redundant requests, analysis of security or technical incidents. It is provided based on monthly donations in the amount of $15+ or similar in any other currency. See details here.


The key difference between ADA and RIC in DNS is that ADA allows various services such as Yandex, TikTok, Facebook, etc. By "various services," we mean services for managing marketing cabinets or business tools.

What Does ADA Allow?

  • Social media tools (e.g., Facebook, Twitter, LinkedIn, TikTok, etc.)
  • All Yandex tools (Alice, Kinopoisk, etc.)
  • All Google tools
  • Advertising links from search results
  • Etc. uses a granular approach. If ADA allows, for example, all Yandex resources, then RIC allows key services (for example: mail, passport, money, etc.). In simple terms, RIC is a more "strict" service that can affect some Internet services.

ADA is an "add-on," adapted and suitable for most users of the DNS service.
