IPv6 CIDR routes for Cloudflare Mesh
Cloudflare Mesh nodes now support IPv6 CIDR routes. You can advertise both IPv4 and IPv6 subnets through your Mesh nodes, making IPv6-only or dual-stack private networks reachable from any enrolled device.
To add an IPv6 route, follow the same steps as adding an IPv4 route — enter the IPv6 CIDR (for example, fd00::/64) when configuring the route in the dashboard or via the API.
