This is the command addr2name that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
addr2name, name2addr - perform DNS lookups from scripts
addr2name [-46cmnr] [HOSTNAMES]
name2addr [-46cn] [HOSTNAMES]
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.
-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 locally configured
addresses (If the system has no IPv4 resp IPv6 address, 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
-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.
Display program version and license and exit.
