IPv6 question

I had a question on my test that freaked me out. I am not IPv6 expert
but anyway

Here is the example

I was given IP prefix (ex. 3008:1234:abcd:ef12::/64)

Then 3rd octet of IPv4 address on the interface needs to be a subnet id
for IPv6.

This is it, how the hell am I suppose to know what ip address I need to
setup?

Please help

Thanks
