NAME
    dig - DNS lookup utility

SYNOPSIS
    dig [ @server ] [ -b address ] [ -c class ]  [ -f filename ] [ -k
    filename ] [ -p port# ]  [ -t type ] [ -x addr ] [ -y name:key ]  [
    name ] [ type ]  [ class ] [ queryopt... ]

    dig [ -h ]

    dig [ global-queryopt... ] [ query... ]

DESCRIPTION
    dig (domain information groper) is a flexible tool for interrogating
    DNS name servers. It performs DNS lookups and displays the answers that
    are returned from the name server(s) that were queried. Most DNS admin-
    istrators use dig to troubleshoot DNS problems because of its flexibil-
    ity, ease of use and clarity of output. Other lookup tools tend to have
    less functionality than dig.

    Although dig is normally used with command-line arguments, it also has
    a batch  mode of operation for reading lookup requests from a file. A
    brief summary of its command-line arguments and options is printed when
    the -h option is given. Unlike earlier versions, the BIND9 implementa-
    tion of dig allows multiple lookups to be issued from the command line.

    Unless it is told to query a specific name server, dig will try each of
    the servers listed in /etc/resolv.conf.

    When no command line arguments or options are given, will perform an NS
    query for "." (the root).

SIMPLE USAGE
    A typical invocation of dig looks like:

 dig @server name type

    where:

    server is the name or IP address of the name server to query. This can
    be an IPv4 address in dotted-decimal notation or an IPv6 address
    in colon-delimited notation. When the supplied server argument
    is a hostname, dig resolves that name before querying that name
    server. If no server argument is provided,  dig consults
    /etc/resolv.conf and queries the name servers listed there. The
    reply from the name server that responds is displayed.

    name  is the name of the resource record that is to be looked up.
