Hello,

No, there's no support for this on the probes. It'd be pretty expensive for
to do this on the fly, as it involves a lookup (into BGP or IRRs) for
virtually every packet received.

But it would be possible to annotate the results in some way, when storing
them or when you access them. Is this something that would be interesting
for others too?

Regards,
Robert


PS: of course the task itself is far from trivial. Trying it out on a random
Linux box gave me the "wrong AS" for almost half of the cases. I'm sure
there could be extensive discussion around how to Do This Right in the first
place :)
