Ummm, what makes you think that people on this list can tell you those things?

Have you checked out RFC 791, the one that specifies IP?

If you want to pull packets apart, you are expected to read up on it
yourself and not ask others. Sheesh, that's the only way you can become a
self-respecting guru.

BTW, you might want to look at Ethereal. It will show you the offsets, and
it may already do exactly what you want. See my sig for location.
