This article is about how we built the new high scalable cloud hosting solution using IPv6-only communication between commodity servers, what problems we faced with IPv6 protocol and how we tackled them for handling more than ten millions active users.

Only frontend (user facing) services are running in dual-stack environment, everything else is IPv6-only for west-east traffic.
