 #### With IPv6 Support
 
-> **Note:** Full IPv6 gateway support (all devices including WiFi) requires FritzBox to be the IPv6 border
-> router. Pi can only act as IPv6 gateway for wired hosts with static `network_ipv6_gateway` config.
-> radvd is deployed by the `gateway` role when `network_ipv6_address` is defined on the Pi.
+> **Note:** IPv6 support is currently disabled due to ISP compatibility issues. The steps below are kept
+> for future reference. IPv6 on the network template defaults to `method=disabled`.
+> To enable: set `method=auto` in `roles/network/templates/eth0-connection.nmconnection.j2` and follow
+> the steps below to obtain a stable ULA address via SLAAC.
+> Use the `mngtmpaddr` address from `ip address | grep "inet6 fd"` as `{{ pihole_ipv6 }}` — not the `temporary` one.
