-h, -?

Display this help and exit.

-t type

If type is "a", print the A record (default). If type is "aaaa", print the AAAA record. If type is "u", look for either AAAA or A record (in that order).

-s 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).
