 - WARP will only exclude local networks in the [RFC 1918](https://datatracker.ietf.org/doc/html/rfc1918) address space. Other IP addresses such as CGNAT are not supported.
 - The maximum excluded subnet size is `/24`.
 - If a device has multiple network interfaces with distinct local IP ranges, WARP will only exclude one of those networks. To access a specific local network, disable the other interfaces and disconnect/reconnect WARP.

+When `Enabled`, the operating system will register WARP's [local interface IP](#override-local-interface-ip) (CGNAT IP or `172.16.0.2`) with your on-premise DNS server when the DNS server is reachable.
+
+If you use on-premise DNS infrastructure (such as Active Directory), we recommend turning this setting on for remote [device profiles](/cloudflare-one/connections/connect-devices/warp/configure-warp/device-profiles/) and turning it off for [managed network](/cloudflare-one/connections/connect-devices/warp/configure-warp/managed-networks/) device profiles. In this configuration, remote devices will register their WARP interface IP, while on-premise devices will only register their local DHCP address. This allows the on-premise DNS server to resolve device hostnames no matter where the device is located.
