ADDR2NAME(1)			  User's Manual 		    ADDR2NAME(1)

NAME
     addr2name, name2addr - perform DNS lookups from scripts

SYNOPSIS
     addr2name [-46cmnr] [HOSTNAMES]

     name2addr [-46cn] [HOSTNAMES]

DESCRIPTON
     Write  addresses  or  canonical hostname of specified names to the standard
     output. If no names are specified via the command line, they are read  from
     the standard input.

OPTIONS
     -4 or --ipv4
	    Only try to perform IPv4 lookups.

     -6 or --ipv6
	    Only try to perform IPv6 lookups.

     -c or --config
	    Only  lookup  and  print results for address families that match lo-
	    cally configured addresses (If the system has no IPv4 resp IPv6  ad-
	    dress, then IPv4 resp IPv6 addresses are ignored).

     -h or --help
	    Display some help and exit.

     -m or --multiple
	    Normally,  if  a name yields multiple results, only the first one is
	    printed.  With this optional parameter, all results will be  printed
	    on a single line, separated by spaces.

     -n or --numeric
	    Prevent  forward hostname lookup.  This ensures that the input names
	    are numeric addresses, which do not need to be looked up.  Typically
	    used  along with the --reverse option to convert numerical addresses
	    to canonical hostnames.

     -r or --reverse
	    Perform a reverse DNS lookup (enabled  implicitly  with  addr2name).
	    addr2name prints numerical resolved addresses by default instead.

     --version
	    Display program version and license and exit.
