VietNam National IPv6 Network was set up and operated by VNNIC. It is based on some separate IPv6 networks: National DNSv6 network, VNIXv6 network, and IPv6 promotion network. All local ISPs can make an IPv6 connection to the promotion network by both native and tunneling methods, while only VNIX members can connect to the VNIXv6 network. The National IPv6 Network provides some kind of basic services for connected members for the purpose of testing.
