fdnsnamep(1)		    General Commands Manual		  fdnsnamep(1)

NAME
       fdnsnamep - resolve an IPv4 or IPv6 address to a	hostname with paranoid
       checking

SYNOPSIS
       fdnsname	_IP address_

DESCRIPTION
       fdnsname	will attempt to	look up	 a  single  hostname  for  IP  address
       (which  is  an IPv4 address in dotted-quad format or an IPv6 address in
       colon-seperated format).	 If one	is found, the program checks  to  make
       sure  that  the	hostname has a corresponding A or AAAA record pointing
       back to the supplied IP.	 If so,	the hostname is	 printed  to  standard
       output and the program exits with return	code 0.	 If the	paranoid check
       fails, nothing is printed and the program exits with return code	3.  If
       no hostname is found, nothing is	printed	and the	program	exits with re-
       turn code 1.
