When you use these selectors in an egress policy for traffic from a supported on-ramp, Gateway will assign initial resolved IPs to the DNS queries, then apply the correct egress IP according to the egress policy. Unsupported traffic will be resolved with your default Gateway settings. Gateway will only overwrite the DNS response when the query matches a condition in the egress policy. If you use [DNS locations](/cloudflare-one/connections/connect-devices/agentless/dns/locations/) to send a DNS query to Gateway with IPv4, IPv6, DoT, or DoH, Gateway will not return the initial resolved IP.

To turn on the selectors for your account, use the [Patch Zero Trust account configuration](/api/resources/zero_trust/subresources/gateway/subresources/configurations/methods/edit/) endpoint. For example:
