Memcached using the intranet IP is possible.
The start parameter is set to 127.0.0.1 with the-l binding address and can only be accessed natively.

Example: memcached-d-M 256-c 2048-p 11211-u www-l 127.0.0.1

Yes, it is good to use the intranet IP when starting up, unless you want to share the data with other servers, then you can add the IP of other servers to the white list of the firewall.
