As for your question, I can tell you clearly that most universities now have IPV6 networks, but if you are a student, you may not enjoy IPV6, because schools generally only open IPV4 to students.

If your school really opens IPV6, XP system needs to install IPV6 protocol. Vista and win7 systems have their own IPV4 protocols, so they can be set automatically.

At present, IPv6 is not popular, most of them are IPV4, and most websites are IPV4.

I hope my answer is helpful to you. Thank you.
