Configuring a hostname	We recommend setting a hostname for your appliance instead of using a hard-coded IP address.	[/enterprise/admin/guides/installation/configuring-hostnames/ /enterprise/admin/installation/configuring-a-hostname /enterprise/admin/configuration/configuring-a-hostname]	[{enterprise-server *}]

If you configure a hostname instead of a hard-coded IP address, you will be able to change the physical hardware that {% data variables.product.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. We also recommend enabling subdomain isolation for the chosen hostname to mitigate several cross-site scripting style vulnerabilities. For more information on hostname settings, see Section 2.1 of the HTTP RFC.

Type the hostname you'd like to set for {% data variables.product.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 %}

After you configure a hostname, we recommend that you enable subdomain isolation for {% data variables.product.product_location %}. For more information, see "[Enabling subdomain isolation](/enterprise/{{ currentVersion }}/admin/guides/installation/enabling-subdomain-isolation/)."
