title: Get all hostnames for an IP address in the network
body: <p>I have a requirement wherein an IP address can have multiple hostnames mapped to it.  I tried looking into <code>InetAddress.getAllByName("10.33.28.55")</code> however I did not get the desired result, it returned just one entry. <code>nslookup</code> on the IP address returns all DNS entries. How do I retrieve all the hostnames associated with this IP address in Java?</p>
