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.

ARGS

@server

Server ip address. May specify multiple in comma delimited format. May be specified in URI format.

	name		Name of the resource record that is to be looked up
	type		What type of query is required. e.g. - A, AAAA, MX, TXT, etc. If not specified, A will be used.
	class		Sets the query class, defaults to IN. May also be HS or CH.

FLAGS

−c class

Sets the query class, defaults to IN. May also be HS or CH.

−h

Prints the help.

−p port

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

−q name

Specifies the domain name to query. Useful to distinguish name from other arguments

	−r		Skip adigrc processing
	−s		Server (alias for @server syntax), compatibility with old cmdline

−t type

Indicates resource record type to query. Useful to distinguish type from other arguments

−x addr

Simplified reverse lookups. Sets the type to PTR and forms a valid in-arpa query string
