the atlas is good stuff, I am curious (OT) if they have added a videoconferencing-like test to it? > like 240.2.3.0/24 to see if it can be reached. I very much would like a study of 240/4. In particular, announcing 255.255/16 might pick up a lot of misconfigured routers out there. Tests of the DNS would also be useful. This test setup has been working for years now... $ host postel.taht.net postel.taht.net has address 85.90.246.167 postel.taht.net has address 255.255.255.254 # wireguard vpn presently postel.taht.net has address 0.0.0.1 # wireguard vpn postel.taht.net has IPv6 address 2a01:7e01:e001:28:f3ee:d002:0:beef # ironically the ipv6 address is down and I hadn't noticed! > > That's at least a decent measurement and report, but the client > side OS will still be a variable that is difficult to digest.
