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)
