Map of test server locations

The map below is an static image of the current DNS-over-TLS test server locations. We don’t show Quad9 on here because they run an anycast service (see their website for details).

The icons reflect the software being used:

  • Green pin: Unbound
  • Pink pin: Knot Resolver
  • Blue pin: TLS proxy in front of a nameserver
  • Blue flag: Unknown
