My router (CH7465VF) auto-updated recently and now forces DHCPv6 usage. I can switch between stateful and stateless but can't disable it nor can I define rules for static IPv6 addresses. The iOS devices I use can't disable IPv6. As a result, all iOS devices use the IPv6 DNS of my ISP as provided via DHCPv6 and no ads are blocked.
Is there any other option to solve this that does not involve flashing my router, adding another WLAN-router or adding configuration profiles to each iOS device?
