  #       exists on the server. It is intended to be set as a default on installation,

  #       for DNS amplification attacks if (accidentally) running public.
  #   - "SINGLE"
  #       Permit all origins, accept only on the specified interface. Respond only to
  #       queries arriving on the specified interface. The loopback (lo) interface is

  #       Make sure your Pi-hole is properly firewalled!
  #   - "BIND"
  #       By default, FTL binds the wildcard address. If this is not what you want, you
  #       can use this option as it forces FTL to really bind only the interfaces it is
  #       listening on. Note that this may result in issues when the interface may go
  #       down (cable unplugged, etc.). About the only time when this is useful is when
  #       running another nameserver on the same port on the same machine. This may also
  #       happen if you run a virtualization API such as libvirt. When this option is
  #       used, IP alias interface labels (e.g. enp2s0:0) are checked rather than
  #       interface names.
  #   - "ALL"

  #       properly firewalled! This truly allows any traffic to be replied to and is a

    # mitigate issues caused by massively outdated DNS replies, the maximum overaging of
    # cached records is limited. We strongly recommend staying below 86400 (1 day) with

  # sign means allow, where a minus sign means deny. If a subnet mask is omitted, such
  # as -1.2.3.4, this means to deny only that single IP address. If this value is not
  # set (empty string), all accesses are allowed. Otherwise, the default setting is to

  # Ports to be used by the webserver.
  # Comma-separated list of ports to listen on. It is possible to specify an IP address
  # to bind to. In this case, an IP address and a colon must be prepended to the port
  # number. For example, to bind to the loopback interface on port 80 (IPv4) and to all
  # interfaces port 8080 (IPv4), use "127.0.0.1:80,8080". "[::]:80" can be used to
  # listen to IPv6 connections to port 80. IPv6 addresses of network interfaces can be
  # specified as well, e.g. "[::1]:80" for the IPv6 loopback interface. [::]:80 will
  # bind to port 80 IPv6 only.
  # In order to use port 80 for all interfaces, both IPv4 and IPv6, use either the
  # configuration "80,[::]:80" (create one socket for IPv4 and one for IPv6 only), or
  # "+80" (create one socket for both, IPv4 and IPv6). The '+' notation to use IPv4 and
  # IPv6 will only work if no network interface is specified. Depending on your
  # operating system version and IPv6 network environment, some configurations might not
  # work as expected, so you have to test to find the configuration most suitable for
  # your needs. In case "+80" does not work for your environment, you need to use
  # "80,[::]:80".
  # If the port is TLS/SSL, a letter 's' (secure) must be appended, for example,
  # "80,443s" will open port 80 and port 443, and connections on port 443 will be
  # encrypted. For non-encrypted ports, it is allowed to append letter 'r' (as in
  # redirect). Redirected ports will redirect all their traffic to the first configured
  # SSL port. For example, if webserver.port is "80r,443s", then all HTTP traffic coming
  # at port 80 will be redirected to HTTPS port 443.
  # When specifying 'o' (optional) behind a port, inability to use this port is not
  # considered an error. For instance, specifying "80o,8080o" will allow the webserver
  # to listen on either 80, 8080, both or even none of the two ports. This flag may be
  # combined with 'r' and 's' like "80or,443os,8080,4443s" (80 redirecting to SSL if
  # available, 443 encrypted if available, 8080 mandatory and unencrypted, 4443
  # mandatory and encrypted).
  # If this value is not set (empty string), the web server will not be started and,
  # hence, the API will not be available.
