Maybe still ISPs suffer poor field reports. I was client at "Kabel Deutschland, Germany" and they offer native IPv6 for their customers, with "Dual stack lite" as the routing option to reach the IPv4 world. It performed poorly for me, perhaps due to bad load balancing of the IPv4-gateways. I switched to a buisness plan (+10EUR/month) of the same ISP and now have an own static IPv4 adress and not even native access to IPv6 any more. This is a clear statement how they think about their IPv6 support.

It's normal, no? They deploy IPv6 because they don't have enough IPv4 addresses. And since most servers in the world are not IPv6 ready and will never be for a long time, if you want to reach an IPv4 server you have to go through their CGNAT which may have a piss-poor performance. I really wish RIPE could force ISPs to release the addresses they don't need :(

  If their CGNAT would perform better, clients would not even notice a difference. I hardly doubt all that buisness clients (thinking of small non-IT buisinesses such as coffee shops) require native IPv4. An ISP who cannot offer a proper IPv6+IPv4 internet access should not be refered to as an ISP. He supports IPv6<->IPv4 segregation, instead.

  12% of all web servers have IPv6, including most of the largest sites. https://w3techs.com/technologies/details/ce-ipv6/all/all https://w3techs.com/technologies/details/ce-ipv6/all/all

    It's worth noting that many of the highest traffic websites are in that 12%, to the point that an average dual-stacked customer will see about 50% of their traffic by volume go over v6. That's a very relevant stat when it comes to provisioning CGNAT capacity for your customer base.

For the record, I'm also on the business plan (cable) with them but seem to have absolutely no troubles with IPv4 and IPv6 and I'm IPv6 native from what I can see here. Are you on DSL by any chance?

  My experiences come from Unitymedia (in Germany), they offer 50-200Mbit over cable TV lines (coax).

  Business plans don't suffer from CGNAT

Same story here with Orange in Spain. Fake dual stack through barely-working CG-NAT limited to ports <2000 which many services/devices do not accept and which the router randomly forgot, and no PPTP VPN because the CG-NAT did not support the GRE protocol. Plus the joys of sharing an IP with random strangers, of course. After many clients started complaining they offered us static IPv4 plans (with no IPv6) for free (normally it costs 12€/month), instead of coming up with a better dual stack implementation.
