Those are the IP address for the MySQL database.

Sounds like you configured your master backend with:

IP address
The IP address of the master backend server. All frontend and non-master 
backend machines will connect to this server.  If you only have one 
backend, this should be the same IP address as above.

set to 127.0.0.1.
