DNS locations are a collection of DNS endpoints which can be mapped to physical entities such as offices, homes, or data centers.

The fastest way to start filtering DNS queries from a location is by changing the DNS resolvers at the router.

## Add a DNS location

To add a DNS location to Gateway:

1. In [Zero Trust](https://one.dash.cloudflare.com), go to **Gateway** > **DNS Locations**.

2. Select **Add a location**.

3. Choose a name for your DNS location.

4. Choose at least one [DNS endpoint](https://developers.cloudflare.com/cloudflare-one/connections/connect-devices/agentless/dns/locations/#dns-endpoints) to resolve your organization's DNS queries.

5. (Optional) Toggle the following settings:

   * **Enable EDNS client subnet** sends a user's IP geolocation to authoritative DNS nameservers. [EDNS Client Subnet (ECS)](https://developers.cloudflare.com/cloudflare-one/glossary/?term=ecs) helps reduce latency by routing the user to the closest origin server. Cloudflare enables EDNS in a privacy preserving way by not sending the user's exact IP address but rather the first `/24` range of the larger range that contains their IP address. This `/24` range will share the same geographic location as the user's exact IP address.
   * **Set as Default DNS Location** sets this location as the default DoH endpoint for DNS queries.

6. Select **Continue**.

7. (Optional) Turn on source IP filtering for your configured endpoints, then add any source IPv4/IPv6 addresses to validate.

   * Endpoint authentication is required for standard IPv4 addresses and optional for dedicated IPv4 addresses.
   * **DoH endpoint filtering & authentication** lets you restrict DNS resolution to only valid identities or user tokens in addition to IPv4/IPv6 addresses.

8. Select **Continue**.

9. Review the settings for your DNS location, then choose **Done**.

Captive portal limitation

Deploying Gateway DNS filtering using static IP addresses may prevent users from connecting to public Wi-Fi networks through captive portals. If users are experiencing connectivity issues related to captive portals, they should:

1. Remove the static IP addresses from the device.
2. Connect to the Wi-Fi network.
3. Once the connection has been established, add the static IP addresses back.

To avoid this issue, use the [WARP client](https://developers.cloudflare.com/cloudflare-one/connections/connect-devices/warp/) to connect your devices to Cloudflare Zero Trust.
