Ipv6 is the future trend, because the address of v4 has been exhausted, and now it is widely popularized in the educational network of colleges and universities. Most schools have unlimited traffic, limited to ipv4 ~ (of course, some good schools also have unlimited traffic in v4, and some schools also have speed limit in V6).

Because the ipv6 access of general schools is 1000Mbps (some schools are1000 Mbps), it is easy to reach the upper limit speed of1000 M network when downloading popular resources, which is close to 12M/s~

Now the public network (China Telecom Unicom) has also opened ipv6 in some places. However, because the access speed between the public network and the education network is not fast, even if the public network has v6, it is difficult to connect the resources of the education network PT in the public network. In addition, public networks are mostly 2M or 4M adsl, which is n times slower than education networks. Needless to say, uploading is also limited, and it is difficult to mix PT without uploading.

I hope I can help you, welcome to ask questions ~
