Examples of org.apache.commons.net.WhoisClient

org.apache.commons.net.WhoisClient
The WhoisClient class implements the client side of the Internet Whois Protocol defined in RFC 954. To query a host you create a WhoisClient instance, connect to the host, query the host, and finally disconnect from the host. If the whois service you want to query is on a non-standard port, connect to the host at that port. Here's a sample use:
```
 WhoisClient whois; whois = new WhoisClient(); try { whois.connect(WhoisClient.DEFAULT_HOST); System.out.println(whois.query("foobar")); whois.disconnect(); } catch(IOException e) { System.err.println("Error I/O exception: " + e.getMessage()); return; } 
```
