Hi,
I use a fine example (Example 7/12) from the book Java Network
Programming by Elliotte Rusty Harold - OReilly publication for this
InterNIC querying . Ofcource there are some deprecated methods present and
also a standalone programme - which I am sure you will able handle yourself.
This application takes 10 seconds typically to return the result . The
example is available at
ftp://ftp.ora.com/published/oreilly/java/java.netprog
The book although is published in 1997 is worth a reading .
Cheers,
Thiru
