Looking at my employers network...

We know the GPS coordinates for each BGP next-hop in the network, and
traffic is sampled on ingress at the edge of the network and reported to
pmacct (*flow), which also receives a RR-style BGP feed for correlation.

We can know where (geographically) a packet enters the network, where it
leaves the network and to what address family it belongs.

However, this would be just one network's (biased) view on things.
