Windows 10: IPv4 only Web pages loading problem - IPv6 are OK

My friend has Windows 10 notebook and has problems with pages that are IPv4 only. I tried ping and it translates addresses well - v4 or v6. But v4 has problems with ping timeout - IPv6 are OK. Pages (v4) doesn't load but after a while they loads. Notebook gets both addresses (v4+v6).
Android phones works well without this problems.
I tried my linux notebook and there are no problems as well.

Friend's NB loads that pages on another WiFi well (I don't know if it gets IPv6 address there)

Thanks for any help ;-)

(I didn't note his Windows 10 version, but will on next visit - should be Win 10 Home )

Connectivity (IPv4/IPv6): Disconnected

Hi,



Thank you for writing to Microsoft Community Forums.



Ideally this Connectivity (IPv4/IPv6): Disconnected, means that the devices in not in use or not connected and it could be any device for example, Ethernet, WIFI, Bluetooth or Local Area Connection.



If you are using WI-FI for internet connection then Ethernet will show Connectivity (IPv4/IPv6): Disconnected.



In order to understand the issue and assist you accordingly, we need some information

• What is your network setup?
  
• Are you seeing any errors?
  
• Where you are seeing this information?

Meanwhile, try the troubleshooting steps referred in this article:

Fix network connection issues in Windows and check if it works.

IPv4 and IPv6 Connectivity?

That is because IPv6 is not used outside of the gateway. Only Homegroup uses it. If you want to use Dual Stack, which uses both IPv4 and IPv6, you would need a router capable of it. Any IPv4 traffic that passes outside the gateway and may direct from your ISP to a server that uses IPv6, it will do so with 6:4. All IPv4 packets are encapsulated in a IPv6 packet and appear to be transparent when they reach the router on the other end, that just sees the IPv6 packet until it gets past the Gateway to be routed to the server, which can be using only IPv4, so it would get a IPv4 packet after the Gateway removes the Encapsulating. It does the reverse when the packet goes back out and gets sent back to you.

You can check your outside the Gateway IPv6 status at IPv6 test - IPv6/4 connectivity and speed test

Depending on your web browser, it may come back and state that DNS fallback failed which is normal. DNS6 + IP6 should also show failed. Everything else should show Green.

The biggest problem right now is that IPv6 still has a lot of security problems with it, so that is why it is still sitting in a test mode. We may never see it become the norm, since there are still more than enough IPv4 addresses available between ISP's and the Backbones. The media hype by the likes of Cisco, etc. is to sell their Dual Stack gear more than anything.
