What routers ae you using? If it's Netlink its easy go to network - and change it to ipv4/ipv6 - save and apply. Restart the router.. If the ipv6 is available you can check it on your pc setting or on the router config page..I will try contacting them .It will be a. hardwork for explaining to them about ipv6. They can just transfer us to ipv6 isn't it ?
There would be a 2000 series address.
