DNS Services

Domain Name System services providing local and forwarded DNS resolution


DNS Services

Domain Name System (DNS) services provide authoritative and recursive DNS resolution for local network domains and internet-wide queries. The DNS infrastructure integrates with DHCP for automatic hostname registration, coordinates with filtering services for privacy and security, and handles special-case domain resolution including Tor hidden services.

DNS Architecture

Complete guide to Pimeleon's DNS infrastructure including BIND9 server configuration, local zone management, dynamic update integration with DHCP, upstream resolver coordination, and special handling for privacy services. Covers hostname registration, zone transfers, and service discovery.

Service Capabilities

  • Local Authority: BIND9 provides authoritative DNS for zen.lan domain and reverse lookup zones
  • Dynamic Updates: DHCP server automatically registers client hostnames in DNS zones
  • Recursive Resolution: Forwarding queries to upstream DNS services for external domains
  • Privacy Filtering: Integration with Pi-hole and DNSCrypt-proxy for filtered resolution
  • Tor Integration: Special handling for .onion domain resolution through Tor network
  • Zone Management: Automatic creation and updates of forward and reverse lookup zones

Configuration Highlights

  • Local Domain: zen.lan zone for internal hostname resolution
  • Reverse Zones: X.168.192.in-addr.arpa and Y.168.192.in-addr.arpa for IP-to-hostname lookups
  • RNDC Security: Authenticated dynamic updates preventing unauthorized DNS changes
  • Service Records: SRV records for NetBIOS and other network service discovery
  • Forwarding Zones: Integration with filtering services for privacy-enhanced resolution
