If you want to make changes to the custom domain, you must delete the existing custom domain and create a new one.\n\nIn the Google Cloud console, follow these steps to customize the domain of your Looker (Google Cloud core) instance:\n\n1. On the **Instances** page, click the name of the instance for which you would like to set up a custom domain.\n2. Click the **CUSTOM DOMAIN** tab.\n3. Click **ADD A CUSTOM DOMAIN**.\n\n This opens the **Add a new custom domain** panel.\n4. Using only letters, numbers, and dashes, enter the hostname of up to 64 characters for the web domain that you would like to use --- for example: `looker.examplepetstore.com`.\n\n5. Click **DONE** on the **Add a new custom domain** panel to return to the **CUSTOM DOMAIN** tab.\n\n| **Note:** Updating the custom domain takes 10 to 15 minutes to complete.\n\nOnce your custom domain is set up, it is displayed in the **Domain** column on the **CUSTOM DOMAIN** tab of the Looker (Google Cloud core) [instance details page](/looker/docs/looker-core-custom-domain-settings) in the Google Cloud console.\n\nAfter your custom domain has been created, you can [view information](/looker/docs/looker-core-custom-domain-settings) about it, or [delete](/looker/docs/looker-core-custom-domain-delete) it.\n\nAccess the custom domain\n\nAfter a custom domain is set up in the Google Cloud console, you must configure your network to allow users to access the domain. To learn more about that configuration for your use case, review the following documentation pages.\n\nAccess a custom domain from the internet:\n\n- [Set up and access a custom domain for a public secure connections Looker (Google Cloud core) instance](/looker/docs/looker-core-custom-domain)\n- [Access a Private Service Connect instance from the internet](/looker/docs/looker-core-psc-access-public)\n\nAccess a custom domain through a private network:\n\n- [Access a Looker (Google Cloud core) instance using private services access](/looker/docs/looker-core-custom-domain-private-ip)\n- [Private inbound access to a Looker (Google Cloud core) instance using Private Service Connect](/looker/docs/looker-core-psc-access)"]]
