NAME
addr2name, name2addr - perform DNS lookups from scriptsSYNOPSIS
addr2name [-46mnr] [HOSTNAMES]name2addr [-46n] [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.
- -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.
