Better not recurse forever, or you'll meet something called a spider trap:
  query bogus1.example.com, tells you about bogus2.example.com
  query bogus2.example.com, tells you about bogus3.example.com
  query bogus3.example.com, tells you about bogus4.example.com
  query bogus4.example.com, tells you about bogus5.example.com
  query bogus5.example.com, tells you about bogus6.example.com
  query bogus6.example.com, tells you about bogus7.example.com
