In my program a user enters a url string, say

how would I get the IP address of this url? I tried using

InetAddress address = InetAddress.getByName(urlStr);

but the result always comes back null. What is the proper way to get the IP address?

Answer

Try this:

InetAddress address = InetAddress.getByName(new URL(urlString).getHost());

To get the raw IP:

String ip = address.getHostAddress();
