Over the years, light cats in many places can get ipv6 Address , And the new routes basically support ipv6, But there are still a lot of people http://test-ipv6.com I can't see my own ipv6 Address , I can't make it ipv6 Website .
I also have this problem , There is a light cat from an unknown mobile manufacturer at home + glory wifi6, Great speed , Just a little regret ： Can't use ipv6. I work and ipv6 There's something about it , I studied for a while ipv6, Decided to solve the problem .
Specific performance ：
- 1. Naked cat 、 The router has ipv6 Address .
- 2. The computer has an Internet ipv6 Address .
- 3. stay test-ipv6 Can't detect... On ipv6.
- 4. ping ipv6 Address display timeout .
Computer access ipv6 The way to the address , There are two kinds of , So maybe there's something wrong with these two ways .
- RA RS The process , In short , It's the computer that sends out RS Inquire about , The router replies RA, And get ipv6 Address process .
- DHCPv6, The router selects an address from the address range to the computer .
First attempt , Failure ：
Look, the lightcat and the router are on dhcp, Doubt is conflict , Close one first .
Okay , After restarting the computer , I got it. ipv6 Address , Can also ping Through the server , But the next day at home ipv6 It doesn't work again ？？？
A second try , success ：
It seems that the problem is not so simple , I carefully observed the light cat and the router ipv6 Address , I found that their addresses didn't match , In theory, , The lower router should inherit the address prefix of optical cat , But I see glory wifi6 The address prefix is another .
So it's not the light cat RA perhaps dhcpv6 There is a problem with the configuration ？
I do the following ：
1. Deselect on light cat M O position , Reduce waiting time . deselect M O position , Can let the client not to request dhcp.
2. The light is off on the cat ipv6 dhcp service .
3. Glory router ipv6 dhcp Choose auto configuration , close ipv6, And turn it on again ipv6, here , The computer got ipv6 Address （ The phone needs to go into flight mode and turn it on ）, can ping Internet access ipv6 Address , Perfect solution ！
