+
+This categorization should help you find the appropriate command more quickly based on the task you need to perform with your Proxmox container.
+
+   - Explain the syntax and provide examples of using these commands.
+
+4. Configuring Container Resources in Proxmox
+   - Describe how to configure container resources, such as CPU, memory, and disk, using Proxmox's web interface or command-line tools.
+   - Cover the use of Proxmox's "Cores," "Memory," and "Disk" configuration options.
+   - Explain how Proxmox leverages cgroups for resource management and isolation.
+
+5. Networking in Proxmox Containers
+   - Discuss the networking options available for containers in Proxmox, such as bridged, NAT, and VLAN modes.
+   - Provide examples of configuring network interfaces and firewall rules for containers.
+
+6. Storage Management for Containers
+   - Explain how to manage storage for containers in Proxmox, including creating and attaching storage volumes.
+   - Cover the different storage types supported by Proxmox, such as local storage, network storage (NFS, iSCSI), and distributed storage (Ceph).
+
+7. Backup and Restoration of Containers
+   - Provide instructions on backing up and restoring containers using Proxmox's built-in backup tools.
+   - Explain how to schedule regular backups and configure retention policies.
+
+8. Monitoring and Troubleshooting

+For your standalone Proxmox setup, switching between static and dynamic IP configurations and managing virtual bridges are important tasks. Below, I'll provide a concise guide to handle these changes effectively and safely.
+
+### Switching from Static IP to DHCP:
+
+- **Backup Configurations:** Always backup configuration files before making changes (`cp /etc/network/interfaces /etc/network/interfaces.bak`).
+
+```bash
+cp /etc/network/interfaces /etc/network/interfaces.bak
+```
+
+**Update Network Interface Configuration:**
+Open `/etc/network/interfaces` in a text editor:
+```bash
+vim /etc/network/interfaces
+```
+- Change the `vmbr0` configuration from static to DHCP:
+```bash
+auto vmbr0
+iface vmbr0 inet dhcp
+    bridge-ports enp3s0
+    bridge-stp off
+    bridge-fd 0
+```
+- Save the changes and exit the editor.
+
+- **Restart Networking to Apply Changes:**
+- Apply the new network settings:
+```bash
+systemctl restart networking
+```
+
+- **Find the New DHCP-Assigned IP Address:**
+- After the network restarts, check the assigned IP:
+```bash
+ip addr show vmbr0
+```
+
+- **Update `/etc/hosts` with the New IP:**
+- Edit the `/etc/hosts` file to replace the old static IP with the new one:
+```bash
+nano /etc/hosts
+```
+- Modify the line with the old IP to the new one you just obtained:
+```plaintext
+192.168.86.62 whitebox.foxtrot.lan whitebox  # Old IP
+192.168.x.x whitebox.foxtrot.lan whitebox    # New DHCP IP
+```
+- Save and exit.
+
+### Creating a New Virtual Bridge (`vmbrX`):
+
+- **Add a New Virtual Bridge Configuration:**
+   - Edit `/etc/network/interfaces`:
+     ```bash
+     vim /etc/network/interfaces
+     ```
+   - Add a new bridge configuration at the end of the file:
+     ```bash
+     auto vmbrX  # Replace X with the next available number
+     iface vmbrX inet manual
+         bridge-ports none
+         bridge-stp off
+         bridge-fd 0
+     ```
+   - Save and exit the editor.
+
+- **Activate the New Bridge:**
+   - Restart the networking service to bring up the new bridge:
+     ```bash
+     systemctl restart networking
+     ```
+
