NAME

       dnsname - recursive reverse lookup for IP address

SYNOPSIS

       dnsname a.b.c.d

DESCRIPTION

       dnsname 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.
