## 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).
