IPV6 education network, namely CERNET2 network, is a core backbone network. . Your home network (assuming that your home is now a small LAN that fully supports IPV6 technology) is also an IPV6 network. . So now that these two networks want to connect, the next step is to need an intermediary to bridge the gap. . This middleman is the Internet Service Provider (ISP). If the ISP does not provide IPV6 service, there is no way to connect them. . Of course, you can make your own tunnel and cross the ISP's IPV4 "river". In that case, you may experience some IPV6 services, but after all, you still occupy the bandwidth of IPV4.
