dig

Overview​

Perform DNS queries and get domain resolution records (read-only).

Command Parameters​

This is a partially read-only command; options are not whitelisted (allowed by default), but the blacklisted parameters below are rejected on match.

Command format:

acli system dig [@<server>] [<domain>] [<type>]

Positional arguments (in declaration order):

@<server>  Optional parameter. 1st positional argument, specify the DNS server to query (@ prefix). Example: @8.8.8.8
<domain>   Optional parameter. 2nd positional argument, specify the domain to query. Example: example.com
<type>     Optional parameter. 3rd positional argument, specify the record type (A/AAAA/MX/NS/TXT, etc.). Example: MX

Forbidden parameters (rejected on match, including GNU unique-prefix abbreviations):

-f|--file=<file>  Batch mode, reads the query list from a file (file read operation). Rejected.
               Because GNU getopt accepts unique-prefix abbreviations, any form starting with
               --f (--f / --fi / --fil) is also rejected. dig has no other long option starting
               with f, so --f is its shortest unique prefix.

Usage Example​

acli system dig @8.8.8.8 example.com
