Hi Tom, Fair point, and thanks for the pointer. I should have mentioned this in my first email: the idea came from bgpmap.sdv.fr (SdV, AS8839). My team used it almost daily for troubleshooting our own network (AS49556) -- it was genuinely useful to us. A few weeks ago it started returning 403 Forbidden, which pushed me to build our own. No intention to compete with anyone here -- HE's tools are great and have been around long before us. This is just a small tool I built for our own troubleshooting and decided to share. It draws the per-prefix map from many vantage points -- that's the part we were missing. It's still new, so feedback is welcome. Matin
