java.net.InetAddress is a class of Internet Protocol (IP) address. This can be either an IPv4 address or an IPv6 address, and in practice you'll have an instance of either Inet4Address or Inet6Address (this class cannot be instantiated directly). Most code does not need to distinguish between the two families, and should use InetAddress.
The method getAllByName() gets all IP addresses associated with the given host identified by name or literal IP address. The IP address is resolved by the configured name service. If the host name is empty or null an UnknownHostException is thrown. If the host name is a literal IP address string an array with the corresponding single InetAddress is returned.
This example list all IP addresses associated with the user enter host name.
Note:
"android.permission.INTERNET" is needed.
For Applications targeting the Honeycomb SDK or higher, cannot attempts to perform a networking operation on its main thread. Otherwise, NetworkOnMainThreadException will be thrown. So the network operation is moved into AsyncTask.
I haven't IPv6 connection currently, I don't know if it will show Inet6Address with IPv6 connection. If you have, please let me know.
