# Hostname Mapping

> Map custom hostnames to specific replicas for serving configuration.

By default, each replica is automatically mapped to be served when the request hostname matches the domain in the replica URL. Hostname Mapping lets you override or extend this by explicitly mapping a custom hostname to a specific replica.

Custom hostname mappings take priority over automatic mappings.

## Adding a hostname mapping

1. Go to **Serving Configuration → Hostname Mappings**
2. In the **New** row at the bottom of the table, enter the hostname to map (e.g. `www.example.com`) and select the target replica from the dropdown
3. Click **Add**

## Deleting a hostname mapping

Click the **Delete (red ✕) icon** next to the mapping you want to remove.
