# Domains

> Manage domains used by tracking links and supported first-party tracking.

Open **Settings → Domains** to manage the domains associated with the current workspace.

## Add a domain

1. Enter the hostname without a protocol or path.
2. Create the DNS record shown by Datalyr.
3. Wait for DNS propagation.
4. Refresh the domain status until it verifies.
5. Set the verified domain as the default when appropriate.

A verified domain can be used by supported tracking links and first-party tracking flows. The primary domain in **Settings → General** identifies the workspace's main website; it is not a substitute for completing domain verification here.

## Before removing a domain

Check active tracking links and installed scripts that use it. Removing the domain can stop those links or installs from working.

See [First-party tracking](/advanced/first-party-tracking) for implementation guidance.
