dnsname - does a reverse lookup for the IP address
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.
