net.bindIp
Type: string
Default: All interfaces. .. versionchanged:: 2.6.0 The deb and rpm packages include a default configuration file that sets {{role}} to 127.0.0.1.
Specifies the IP address that mongos or mongod binds to in order to listen for connections from applications. You may attach mongos or mongod to any interface. When attaching mongos or mongod to a publicly accessible interface, ensure that you have implemented proper authentication and firewall restrictions to protect the integrity of your database.
To bind to multiple IP addresses, enter a list of comma separated values.

Playbooks are expressed in YAML format (see YAML Syntax) and have a minimum of syntax, which intentionally tries to not be a programming language or script, but rather a model of a configuration or a process.
