The ability to retrieve the TTL field of from a packet, such as DatagramPacket.


Mail message:

This sounds reasonable. This is one of the many small features that are
currently missing from the networking API. I'll file an RFE.

P.S. The TTL field and the numbers of routers taken are related but distinct
things. To deduce the numbers of routers through which the packet passed
you need to know the original TTL number. If you control both peers, that's
easy to do, but if you don't it isn't.
