# Remove an IP from an authenticated domain. ## API Overview An authenticated domain allows you to remove the "via" or "sent on behalf of" message that your recipients see when they read your emails. Authenticating a domain allows you to replace sendgrid.net with your personal sending domain. You will be required to create a subdomain so that SendGrid can generate the DNS records which you must give to your host provider. If you choose to use Automated Security, SendGrid will provide you with 3 CNAME records. If you turn Automated Security off, you will get 2 TXT records and 1 MX record. Domain Authentication was formerly called "Domain Whitelabel". For more information, please see [How to set up domain authentication](/docs/sendgrid/ui/account-and-settings/how-to-set-up-domain-authentication/). > \[!NOTE] > > Each user may have a maximum of 3,000 authenticated domains and 3,000 link brandings. This limit is at the user level, meaning each Subuser belonging to a parent account may have its own 3,000 authenticated domains and 3,000 link brandings. ## Operation overview ```json {"path":"https://api.sendgrid.com/v3/whitelabel/domains/{id}/ips/{ip}","method":"delete","servers":[{"url":"https://api.sendgrid.com","description":"for global users and subusers"},{"url":"https://api.eu.sendgrid.com","description":"for EU regional subusers"}]} ``` **This endpoint allows you to remove an IP address from that domain's authentication.** ## Operation details ### Authentication API Key ### Headers ```json [{"in":"header","name":"Authorization","required":true,"default":"Bearer <>","schema":{"type":"string"}},{"name":"on-behalf-of","in":"header","description":"The `on-behalf-of` header allows you to make API calls from a parent account on behalf of the parent's Subusers or customer accounts.

When making a call on behalf of a Subuser, the property value should be the Subuser's username (e.g., `on-behalf-of: `).
