PSNC-EXT-PUB1-EDU: This is the primary external network that provides connectivity to the public internet. It allows virtual machines to interact with external systems and services directly. This network is typically used for purposes that require public access, such as SSH connectivity, hosting web services, external APIs, or any service needing direct internet exposure.
- PSNC-EXT-IPV6-PUB2-EDU: This is IPv6 external networks that provides connectivity to the public internet using IPv6.
PSNC-INTERNAL-LAN: This network is designed for internal use and is accessible only through a secure VPN connection. It provides a private pool of floating IPs that are accessible via VPN only, allowing for secure internal communications and services that do not require to be exposed by public internet access.
PSNC-STORAGE-MANILA: Dedicated to storage operations, this network is specifically for managing and accessing shared file systems via the Manila service in OpenStack. PSNC-STORAGE-MANILA connects VMs to storage resources, providing high-performance access for data-intensive applications and persistent storage needs.

Floating IPs are required to expose a VM to the public internet using IPv4. These IPs are mapped to internal private IPs and enable your VMs to communicate externally. IPv6 addresses are exposed to the public without using floating ip.
Reserving a Floating IP: Floating IPs can be reserved from the PSNC-EXT-PUB1-EDU network using the OpenStack dashboard or CLI. Ensure you select the correct external network (PSNC-EXT-PUB1-EDU) when reserving the IP.
Assigning the IP to a VM: Once reserved, the floating IP must be associated with a VM. This process maps the public floating IP to the VM’s private IP, enabling external access. You can assign the IP to a specific network interface (port) on the VM, allowing it to communicate with external systems.
