  # The device-tracker somehow insists on doing an uncached DNS lookup *every*
  # *single* *time* it talks with DD-WRT (for both the A- and AAAA-record),
  # leading to an absurd skewing of Pi-hole's statistics (50% of _total_
  # requests are for this singular purpose).
  # Even after setting up resolvctl properly on Ubuntu (and configuring Docker
  # to use 127.0.0.53 as DNS instead of talking directly with Pi-hole) it's
  # still doing so...
  # As such, the above (and below) "workarounds" appear to be necessary.
