Hello Richard,

For the IPv4 test, IPvFox says I am connected via IPv4 but the
button still says "Connected via IPv6". I know why that is, I ran
into that problem before.;-)
Why?
This part:
<center>
<a href='
https://ipv6-test.com'><img src='
https://v4v6.ipv6-test.com/imgtest.png' alt='ipv6 test' title='ipv6 test' border='0' /></a>
<!--<a href='

</center>
Even when I use ipv4.menedetter.net and so have my system connect to your's by IPv4, the above code is executed on MY system and it calls ipv6-test.com over IPv6 because my system supports IPv6. And so ipv6-test.com reports that I connect by IPv6.
The button reports how I connect to ipv6-test.com, not how I connect to YOU.
The speedtest is not extremely accurate, but IMO it is good
enough to get an estimate.
My provider says I have 50/5
For IPv4 it sounds good.
Question is why is IPv6 so much slower.
I don't know. But it is not incidental. The speed varies a bit but the difference between IPv4 and IPv6 is consistent. IPv6 speed is about half of IPv4.
And if the problem is on my side or yours or both ;)
Other dual stack speed tests perforned from here show no consistent sigificant difference between IPv4 and IPv6...
Cheers, Michiel
