Convert IPv6 address to decimal

Question

How do we convert an IPv6 address to its decimal equivalent using java?
I could find different tools on Internet but not the java code for the same.
Any help would be much appreciated.
Thanks.

Hello EJP
Please visit the following URL:

This converts the IPv6 address (which is in hexadecimal format) to a decimal number.
I need to implement this functionality. I could not find any method in java.net.Inet6Address class for this.
To convert an IPv4 address which is in String format to its decimal equivalent, we can use following method:
<code>
long stringToLong(String ipAddress) {
          String[] octets = ipAddress.split("\\.");
          long intValue = 0;
          long currentOctet;
          for (int i = 0; i < octets.length; i++) {
               currentOctet = new Integer(octets[(octets.length-1)-i]).intValue();
               intValue = (currentOctet << i*8) | intValue;
          return intValue;
</code>
