Thanks @superseb, able to create pods with both both ipv4 and ipv6 addresses assigned to them.
Now I need to connect to outside IPv6 network but that is failing as of now. Please help with changes needed to achieve that.
If any service needs to be created how do I create it with IPv6 address ?

The node is having global IPv6 address but pods are assigned link local IPv6 addresses and I believe service will also get link local address only. So does this needs to be changed in any way to connect to outside IPv6 network ?
