# Example: |

# |

# _find_zone first.second.third.co.uk |

# |

# ... will return the first zone that exists in admin out of these: |

# - "first.second.third.co.uk" |

# - "second.third.co.uk" |

# - "third.co.uk" |

# - "uk" <-' |

# https://github.com/hlandau/acme/blob/master/_doc/dns.hook |

# - that's better if there are multiple pages. It's so much simpler. |
