NAME

       dnsname - does a reverse lookup for the IP address

SYNOPSIS

       dnsname a.b.c.d

DESCRIPTION

       dnsname does a reverse lookup for the IP address a.b.c.d.  It prints the first domain name
       for that address.  If no domain names are listed in DNS, dnsname prints a blank line.  You
       can list several IP addresses; dnsname prints each result on a separate line.

       There  is  also a dnsfilter(1) program that reads IP addresses from its input and performs
       many reverse lookups in parallel.

       Normally dnsname exits 0.  If dnsname encounters a temporary problem that prevents it from
       determining the domain name, it prints an error message and exits 111.
