Constructing an InetAddress from a byte[]

[Dillinger4]

After reading a question on this topic over at jguru i tried to figure out how an InetAddress object could be constructed using an ip address in the form of a byte[].

Figuring the ip address is most likely a String(say if a host is resolved to an IpAddress) i tried to construct a byte array to make another InetAddress object but the code simply fails because the byte array is too long.

InetAddress inet = InetAddress.getByName("www.sun.com");
String ip = inet.getHostAddress();
System.out.println(ip);
InetAddress inet2 = InetAddress.getByAddress(ip.getBytes());
System.out.println(inet2.getHostAddress());

Even hardcoding the values of the ip address into a byte[] wouldn't work since java dosen't have unsigned primative types.
