Previously I was with Bell Canada, and the public IP address they provided me is xxx.xxx.xxx.xxx.



It was something like 172.16.254.1 which is what Google told me, and also what running ipconfig told me.



However now I am with Rogers, and their public IP address is something very different. Google tells me its 2607:fea8:....




  1. What is this new address? Even ipconfig and Google already tells me this.


  2. However, going on http://www.whatsmyip.org/, it says my public IP address is 99.226.xxx.xxx. Why is this website saying another thing?


  3. If I want to port forward and play games with my friend, which "IP" do I give them to connect on my server?



Thanks

You seem to have both an IPv4 and IPv6 address. If you check your address on a site that supports IPv6, you see your IPv6 address. If you check your address on a site that only supports IPv4, you see your IPv4 address. Some sites are special designed to show you both addresses, for example myip.tf.



As for which address to use, both should work if the other end also supports the same IP version. But maybe your IPv4 address is easier to remember?



That being said, 172.16.. is a private range, so I doubt that’s your real address.

    Your provider provides you with an IPv6 address: 2607:fea8:.... However, large parts of the internet do not use IPv6 yet, they are IPv4-only. The problem with IPv4 is that there's a shortage, so providers do not provide a unique IPv4 address to every single customer. Instead, they offer connectivity to IPv4-only parts of the internet by NAT'ing a large number of IPv6 addresses via one IPv4 address. So a large number of customers share one IPv4 address. As a result, you do not see that IPv4 address on your interface in the ipconfig output, but an IPv4-only website like the one you used to check your IP-address will show it.



    Since you do not have a unique IPv4 address, you cannot host any services. The only public address you can offer to your friends for playing games over the internet, however that would (a) require them to have IPv6 connectivity as well and (b) for the game to support IPv6.

      If a game doesn't support IPv6, perhaps OP could use a VPN server that has its own IP addressing scheme, and play games over that tunnel. Of course, it doesn't work for random people, only those you know.
