Add any additional description here
Look up the DNS A or AAAA record associated with HOST (a hostname or an IP address).
This utility comes with the c-ares asynchronous resolver library.
-d Print some extra debugging output.
-h, -? Display this help and exit.
-t type If type is "a", print the A record. If type is "aaaa", print the AAAA record. If type is "u", look for both AAAA and A records (default).
-s server Set the server list to use for DNS lookups.
-D domain Specify the domain to search instead of using the default values from
/etc/resolv.conf. This option only has an effect on platforms that use
/etc/resolv.conf for DNS configuration; it has no effect on other platforms (such as Win32 or Android).
