title: INET_NTOA and INET_ATON in Java?
body: <p>I use Java (with Spring framework) and want to convert between numeric representations of IPv4 addresses (e.g. 2130706433) and their textual counterparts (e.g. <code>127.0.0.1</code>). Often, methods for doing this are supplied in programming languages (they're usually called <code>INET_NTOA</code> and <code>INET_ATON</code> respectively) but I can't find it in Java. </p>
  
  <p>Anybody knows what they're called or how to implement them?</p>
