What if it switches back between ipv4 and 6? I've seen that some days when I put in "whats my ip" to google it sends back an ipv6 address but today I did it and its ipv4. I thought once your area or ISP switched you didnt go back.
Your correct, but you should have what we call Dual-Stack so both an IPv4 address and an IPv6 address. Check your ipconfig and make sure you have both.
