+## Dynamic Inventory
+
+Use dynamic inventory to fetch host information at runtime:
+
+### Example Usage
+
+```yaml
+- name: Fetch hosts from external source
+  ansible.builtin.get_url:
+    url: "https://api.example.com/hosts"
+    dest: "hosts.json"
+  register: inventory_data
+
+- name: Display inventory hosts
+  debug:
+    var: inventory_data.content
+
+# Example dynamic inventory script (hosts.py):
+# import json
+# print(json.dumps({"hosts": ["web1", "web2"], "groups": {"webservers": ["web1", "web2"]}}))
+``` 
+
+### Common Inventory Sources
+
+1. **EC2 Inventory**:
+   - Uses AWS API to list instances
+   - Parameters: `aws_access_key_id`, `aws_secret_access_key`, `region`
+   - Example:
+     ```bash
+     ansible-inventory --list --inventory=ec2.py
+     ```
+
+2. **OpenStack Inventory**:
+   - Connects to OpenStack neutron API
+   - Parameters: `auth_url`, `project_name`, `username`, `password`
+   - Example:
+     ```bash
+     ansible-inventory --list --inventory=openstack.py
+     ```
+
+3. **Custom Scripts**:
+   - Write Python scripts to generate inventory
+   - Must output JSON in this format:
+     ```json
+     {
+       "hosts": ["host1", "host2"],
+       "groups": {
+         "webservers": ["host1", "host2"]
+       }
+     }
+     ```
+
+### Best Practices
+
+- Use `ansible-inventory --list` to verify inventory structure
+- Test dynamic inventory with `--check` flag
+- Store credentials securely using Ansible Vault
+- Combine with `--limit` to target specific hosts/groups
+
+### Troubleshooting
+
+Use `--debug` flag to see inventory resolution process:
+```bash
+ansible-playbook site.yml --limit="webservers" --debug
+```
