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
