Just did a traceroute to ipv4.jamieweb.net (ipv4 only site with IP: 157.230.83.95) and was surprised to see IPv6 connectivity to a non IPv6 site. But when I try to ping the IP address of the site, I see IPv4 connectivity. Same is seen when trying to speedtest to speedbhu1.jioconnect.com which is IPv4 only.
They are using reserved IPv6 addresses for IPv4 over IPv6 connectivity (64:ff9b::9de6:535f)
