Issues with IPv6 routing

Drinky — Mon, 07 Mar 2022 09:13:03 GMT

For YEARS I've been having issues with IPv6 based websites loading in incomplete or not at all. This is VERY noticeable when using Youtube where it loads in slowly or not at all, giving me a message that I'm not connected to the internet. Using a pingplotter I can easily see a massive packet loss happening when trying to connect to youtube over IPv6. Going to YouTube over IPv4 is fine, hardly any packet loss and good routing. I started noticing this behavior when I was using a VPN. With my VPN on I have no issues reaching youtube, but without it I would often fail to load a video or the whole site would load in slowly. A pingplotter also shows this.

I came across this old thread here:

https://forum.vodafone.de/t5/St%C3%B6rungsmeldungen-Internet-TV/Probleme-mit-IPv6-Verbindungen-bei-vielen-Anschl%C3%BCssen/td-p/2427479/page/

It seems that those issues have still not been resolved 2 years later despite Vodafone saying that there's nothing wrong. Can you guys please fix your terrible IPv6 routing or at least give us the option to disable IPv6 routing in general? I feel like this is an issue that probably plagues a lot of people but since most people don't have any technical knowhow they just chalk it up to their internet being slow while in fact their speeds are fine and it's just Vodafone's routing that is bad. I've attached both of my pingplotter results so you can see for yourself.

Hello Drinky,

thank you for the two tests. However, there is no packet loss at the end of either test. A loss is also shown as a red bar in the lower diagram and this is not the case with you.

By way of explanation, the loss at the top is shown because the server does not respond to the ping request but the file is silently passed on to the next one.

Regards

Jens

We are not talinkg about losing packages, but with slow response from your equipements (IPv4/IPv6 devices with issues are at your end Vodafone)

Packages are not lost (no lost from Devices to Router and from Devices to external services).

Internet speed is right (800+ Mbps download and 50 Mbps upload).

The problem is with the routing, I acknowledge the same issue, slow opening some webpages (even websites in Germany or Ireland) but the problem dissapeared after using a VPN.

It's a routing issue, you need to fix that Vodafone.

I can confirm the "slow" issue / routing regarding ipv6 and several services.

Currently I have massive issues regarding PayPal. As I deactivate the ipv6 interface on my computer its working like expected ("fast").
