DESCRIPTION
    Sample screenshot 1:

FUNCTIONS
  resolvetable
    Usage:

     resolvetable(%args) -> [status, msg, payload, meta]

    Produce a colored table containing DNS resolve results of several names
    from several servers/resolvers.

    This function is not exported.

    Arguments ('*' denotes required arguments):

    *   action => *str* (default: "show-addresses")

        The default action is to show resolve result ("show-addresses").
        Will highlight the majority result with green, and minority result
        with red. Failed resolve (undef) will also be highlighted with a red
        "X".

        The "compare-addresses" action is similar to "show-addresses", but
        will assume the first server/resolver as the reference and compare
        the results of the other servers with the first. When the result is
        different, it will be highlighted with red; when the result is the
        same, it will be highlighted with green. Failed resolve (undef) are
        highlighted with a grey X (if result is the same as reference
        server) or a red X (if result is different than reference server).
        So basically whenever you see a red, the results of the other
        servers are not identical with the first (reference) server.

        The "show-timings" action will show resolve times instead of
        addresses, to compare speed among DNS servers/resolvers. Will
        highlight the fastest server with green.

    *   colorize => *bool* (default: 1)

    *   names* => *array[str]*

    *   servers* => *array[str]*

    *   type => *str* (default: "A")

        Type of DNS record to query.

    Returns an enveloped result (an array).

    First element (status) is an integer containing HTTP status code (200
    means OK, 4xx caller error, 5xx function error). Second element (msg) is
    a string containing error message, or 'OK' if status is 200. Third
    element (payload) is optional, the actual result. Fourth element (meta)
    is called result metadata and is optional, a hash that contains extra
    information.

    Return value: (any)
