4. Select **Manage**.
5. You can exclude or include routes based on either their IP address or domain. When possible we recommend adding an IP address instead of a domain. To learn about the consequences of adding a domain, refer to [Domain-based Split Tunnels](/cloudflare-one/connections/connect-devices/warp/configure-warp/route-traffic/split-tunnels/#domain-based-split-tunnels).

When a user goes to the domain, the domain gets resolved according to your Local Domain Fallback configuration (either by Gateway or by your private DNS server). WARP Split Tunnels will then dynamically include or exclude the IP address returned in the DNS lookup.

You can add up to 1,000 combined Split Tunnel and [Local Domain Fallback](/cloudflare-one/connections/connect-devices/warp/configure-warp/route-traffic/local-domains/) entries to a given device profile.

We recommend keeping the Split Tunnels list short, as each entry takes time for the client to parse. In particular, domains are slower to action than IP addresses because they require on-the-fly IP lookups and routing table / local firewall changes. A shorter list will also make it easier to understand and debug your configuration.
