By default, Globus Connect Server uses a Globus-operated DNS service to provide DNS names to access collections and the Globus Connect Server management API. These names are randomly issued subdomains of the data.globus.org domain.
The globus-connect-server endpoint domain update command configures the domain and certificate used by a endpoint to be one that the administrator controls. The domain may be a wildcard on standard A or AAAA record. The certificate and key may be either managed by or unmanaged by Globus.
