We recommend setting a hostname for your appliance instead of using a hard-coded IP address. This lets you change the physical hardware that GitHub Enterprise runs on without affecting users or the client software.
With a hostname set, you can also enable subdomain isolation.
Note: Your hostname should include a period (.) and be made up of only lowercase letters. This complies with Section 4.3.2 of the HTTP RFC. Otherwise, some browsers may not properly resolve your hostname.
