My laptop used to got ipv6 address. It can not get after some updates. I am sure the school network has ipv6 cz another pc has been used ipv6 for almost a year.
as for now, if I boot into windows11, I can get ipv6 add like 2001:xxxx. If I boot into linux, ipv6 got fe80:xxx(which is not a valid ipv6 add).
This situation occurred once in last year at August. I call IT and they check school network is ok with ipv6. Then they teach me how to kick my laptop off the school network. I tried sometimes then I can use ipv6 again. So this time I tried that way, too. But not work…
Any advice is welcome.
