There are various BGP looking glass servers that can enable you to see the output of various things like this. Better still is some of the 'bgplay' tools that are out there. For example, RIPE hosts one here: https://stat.ripe.net/widget/bgplay https://stat.ripe.net/widget/bgplay This gives a nice graphical diagram of the way BGP routes have changed over the past few days to a server of your choice. If you stick in an Internet address that has changed paths recently (e.g. 131.111.150.25 would currently be such an example), you'll then see how the BGP paths have changed, and what ASNs the traffic has travelled through. Very useful for debugging potential network problems.
