FUNCTIONS

resolvetable

Usage:

 resolvetable(%args) -> [$status_code, $reason, $payload, \%result_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 ($status_code) is an integer containing HTTP-like status code (200 means OK, 4xx caller error, 5xx function error). Second element ($reason) is a string containing error message, or something like "OK" if status is 200. Third element ($payload) is the actual result, but usually not present when enveloped result is an error response ($status_code is not 2xx). Fourth element (%result_meta) is called result metadata and is optional, a hash that contains extra information, much like how HTTP response headers provide additional metadata.

Return value: (any)
