NAME¶

adig - print information collected from Domain Name System (DNS) servers

SYNOPSIS¶

adig [@server] [-c class] [-p port#] [-q name] [-t type] [-x addr] [name] [type] [class] [queryopt...]

DESCRIPTION¶

Send queries to DNS servers about name and print received information, where name is a valid DNS name (e.g. www.example.com, 1.2.3.10.in-addr.arpa).

This utility comes with the c-ares asynchronous resolver library.

It is possible to specify default arguments for adig via ${XDG_CONFIG_HOME}/adigrc.

FLAGS¶

-c class

-p port

Sends query to a port other than 53. Often recommended to set the port using @server instead.
