# Host Inventories
When you are deploying playbooks, you target hosts that exist in "Inventories". These inventories consist of a list of hosts and their corresponding IP addresses, as well as any host-specific variables that may be necessary to declare to run the playbook. You can see an example of my Bunny Lab inventory file at the time of writing this document, below:
When you are deploying playbooks, you target hosts that exist in "Inventories". These inventories consist of a list of hosts and their corresponding IP addresses, as well as any host-specific variables that may be necessary to declare to run the playbook. You can see an example inventory file below. Keep in mind the "Group Variables" section varies based on your environment. NTLM is considered insecure, but may be necessary when you are interacting with Windows servers that are not domain-joined. Otherwise you want to use Kerberos authentication. This is outlined more in the [AWX Kerberos Implementation](https://docs.bunny-lab.io/Servers/Automation/Ansible/AWX/AWX%20Kerberos%20Implementation/#job-template-inventory-examples) documentation.
!!! note "Inventory Data Relationships"
An inventory file consists of hosts, groups, and variables. A host belongs to a group, and a group can have variables configured for it. If you run a playbook / job template against a host, it will assign the variables associated to the group that host belongs to (if any) during runtime.
