Many websites, such as Google, are both IPv4 and IPv6 Dual-line access. www.google.com resolution corresponds to many IP addresses, both IPv4 and IPv6. By default, the DNS server returns multiple IP addresses, while the local machine automatically selects the host based on the response speed of each address.
Generally, people will modify the hosts file in the system directory and specify the Google address as the IPv6 address so that the local machine does not access the DNS server, and directly obtain the IP address from the Local Machine for access.
In fact, you can use a more concise method without having to modify the hosts file.
At present, some public organizations have already provided IPv6-only DNS servers. When an IPv6 server is configured, IPv6 addresses can be returned (and IPv4 addresses are also returned ). (Note: At present, GFW does not block IPv6 DNS, so you can use this method to break through some sites not allowed by gFW .)
Set the IPv6 DNS address:2001: 470: 20: 2
You can easily access all IPv6 websites. Of course, the premise is that all resolved addresses have the fastest IPv6 address response speed. An extreme solution is to disable the IPv4 protocol, however, it seems that many people do not like the era without IPv4 networks, at least for the time being.
After the configuration is complete, almost all Google products can be accessed through IPv6! Cool!
Enjoy the new (future) Internet protocol!
