Specify a Binding Host Name to have Essbase bind only to the IP address for the specified Binding Host Name. Otherwise, at startup, Essbase binds on all available IP addresses.
In EPM 18.104.22.168 / 22.214.171.124 releases, use "ESSBASESERVERHOSTNAME server_name" that identifies the host where your Essbase application process runs. The value must be a valid host name and must map to an IP address assigned to the computer. If ESSBASESERVERHOSTNAME is not specified in essbase.cfg, Essbase and the applications listen on all interfaces (IP_ANY).
For details on this refer to Essbase Tech Ref
In EPM 126.96.36.199 release, in Configure Essbase Server specifies the host name (in Binding Host Name field) to which Essbase Agent and Essbase Server bind and where an Essbase application process runs.
