What Is Unbound?


Unbound is a validating, recursive DNS resolver. Instead of forwarding queries to Google (8.8.8.8) or Cloudflare (1.1.1.1), Unbound resolves domains by querying root servers directly.


Why Recursive DNS?


  • No third-party DNS provider sees your queries
  • DNSSEC validation
  • Maximum DNS privacy
  • No single point of trust

    • Unbound + Pi-hole/AdGuard Home


    The common setup:

    1. Pi-hole/AdGuard Home blocks ads at DNS level

    2. Allowed queries are forwarded to Unbound

    3. Unbound resolves directly from root servers

    4. No external DNS provider involved


    Features


  • DNSSEC validation
  • DNS-over-TLS
  • DNS-over-HTTPS
  • Aggressive caching
  • Prefetching
  • Response rate limiting

    • Deployment


    Deploy on TinyPod or alongside Pi-hole. Resources: 1 CPU, 64 MB RAM.


    Unbound completes the privacy-focused DNS stack. Your DNS queries never touch a third-party resolver.
