1) Using libcurl without a proxy, the verbose options shows "Trying ip address" and nothing else. If restricted to IPv4 it shows only one line. If IPv6 is permitted, I get a first response that network is not reachable and then a second response "Trying ..." which hangs.
Some issue with your ISP and IPv6. A 6to4 solution or a native-IPv6? What if you do 'tracert.exe -6 2a04:4e42:200::81' I'm on Win-10 and it shows 8 hop to Holland. When I had a 6to4 solution from Telenor, most of my IPv6 traffic went via Los Angeles!
