| Configuring a hostname | We recommend setting a hostname for your appliance instead of using a hard-coded IP address. |

|
If you configure a hostname instead of a hard-coded IP address, you will be able to change the physical hardware that {% data variables.location.product_location %} runs on without affecting users or client software.
The hostname setting in the {% data variables.enterprise.management_console %} should be set to an appropriate fully qualified domain name (FQDN) which is resolvable on the internet or within your internal network. For example, your hostname setting could be github.companyname.com. Web and API requests will automatically redirect to the hostname configured in the {% data variables.enterprise.management_console %}. Note that localhost is not a valid hostname setting.
Hostnames must be less than 63 characters in length per Section 2.3.4 of the Domain Names Specification RFC.
After you configure a hostname, you can enable subdomain isolation to further increase the security of {% data variables.location.product_location %}. For more information, see "Enabling subdomain isolation."
For more information on the supported hostname types, see Section 2.1 of the HTTP RFC.
{% data reusables.enterprise_installation.changing-hostname-not-supported %}
{% data reusables.enterprise_site_admin_settings.access-settings %}
{% data reusables.enterprise_site_admin_settings.management-console %}
{% data reusables.enterprise_management_console.hostname-menu-item %}
4. Type the hostname you'd like to set for {% data variables.location.product_location %}.
5. To test the DNS and SSL settings for the new hostname, click Test domain settings.
{% data reusables.enterprise_management_console.test-domain-settings-failure %}
{% data reusables.enterprise_management_console.save-settings %}
To help mitigate various cross-site scripting vulnerabilities, we recommend that you enable subdomain isolation for {% data variables.location.product_location %} after you configure a hostname. For more information, see "Enabling subdomain isolation."
