Reverse traceroute is a tool and protocol extensions to give you information about the return path, i.e. the bits of the path that regular traceroute is not showing you. We have presented it to the operator community at DENOG14 with good support. You can find the protocol extensions here: https://datatracker.ietf.org/doc/html/draft-heiwin-intarea-reverse-traceroute-01 The implementation has progressed, which now fully supports both v4 and v6. If you only want to experiment with the client, a few public server instances can be found here: https://github.com/HSAnet/reverse-traceroute/blob/main/ENDPOINTS If you want to host a server yourself and make is publicly available talk to us. Both server and client code can be found here: https://github.com/hsanet/reverse-traceroute All information regarding reverse traceroute is collected here, including the video on it, given at DENOG14: https://net.hs-augsburg.de/en/project/reverse-traceroute/ Happy to receive comments, feedback and suggestions.
