I can ping some sites no problem and get an IPv4 reply. However on some others, it resolves the address in IPv6 and then hangs. If I ping -4 it works OK.</P><P>This happens on multiple devices (Windows 7, Windows 10, Ubuntu, Android ) so seems to be something on the hub or at BT.</P><P>e.g I can ping bbc.co.uk but not google.co.uk</P><P>If I use the Windows 10 laptop (which shows the symptom on my network) on someone else's network or on my phone hotspot then it is OK.</P><P>This causes browsing issues e.g on <A href="http://www.bbc.co.uk" target="_blank">www.bbc.co.uk</A> it starts OK but then when the page calls ibbc.co.uk it hangs.

At the moment this is my solution, so I guess I can stay that way but it feels like something is wrong somewhere.</P> Wed, 13 Oct 2021 18:51:58 GMT liebls 2021-10-13T18:51:58Z https://community.bt.com/t5/Archive-Staging/IPv6-issue/m-p/2188656#M1234302 <P>I have a strange issue on my home network connected through BT home hub 6 which has only occurred recently.
