Windows clears the stateless ipv6 address in the network adapter and regenerates it

This article was published on 4 years ago , the content may be different from the actual situation. If there are errors in the article, please correct them. I will modify or hide the article according to the situation

Maybe because Unicom replays PPPoE irregularly, my machine (normally on) has 9 IPv6 addresses and countless temporary IPv6 addresses in one night (the effect is as shown in the figure)

Just like this, it's OK, but after some tests, it is found that although the adapter interface shows that the IPv6 status is Internet, it cannot be connected to the network
Because it is a stateless address, ipconfig /release6 and ipconfig /renew6 Two commands don't work

After a try, it is found that turning off and reopening the routerdiscovery function can achieve this effect

 netsh int ipv6 set int LAN routerdiscovery=disable netsh int ipv6 set int LAN routerdiscovery=enable

(where LAN is the name of the network card)

At present, it is configured to schedule a task to run once every morning. First, configure it for a few days to see the effect

PS: Now change the router to stateful and block the route announcement. At least, there will be no IP on the machine
