Title:
  systemd-resolved uses domain limited DNS servers for all requests
  potentially a privacy issue

Status in systemd package in Ubuntu:
  Triaged

Bug description:
  When configuring a DNS server for a link for specific domains (via the
  Domains= ~foo syntax) systemd-resolved correctly routes requests for
  those domains to that DNS server.  However even without ~. on the list
  it also routes all other requests there (and in parallel to the
  primary servers) appearing to pick the fastest responder.  This (to my
  mind) represents a privacy issue as requests that that DNS server is
  not intended to see are routed there.

  I would have expected the ~. syntax to allow me to request this
  behaviour and in its absence to not see general requests routed to
  these servers.
