Ipv6 doesn't work after waking up from sleep mode

Hi All,

I had a problem about ipv6 on windows 7 for a long time. I have a ipv6 & ipv4 dual stack network.
Every time I wake up my computer, the ipv6 cannot work. The appearance is that I can't ping and access ipv6 website.
But after some research, I realize that only the DNS part is broken.
When I ping the ipv6 site like ipv6.google.com, it tells me it find no host, but if I use nslookup, I can find the ipv6 address. And the following are my tries:
ping ipv6.google.com          -- not work
ping 2a00:1450:8001::68    -- does work, the ip is the ipv6.google.com address
ping -6 ipv6.google.com      -- does work like the above

Thanks for your reading, any suggestion will be appreciated.

Just Do It
