How to calculate the USPVM IP addresses from the Serial number

I didn't blog technical for such a long time and I hope this won't bore (I mean non-nerds) you.
Therefore I will keep it short and straight.

HOW? From serial number to obtain the IP addresses (USPVM,Sun 9985V and other equipvalent OEM)

This is what google can't even tell you how (maybe in future google can after stealing my page lol)
