Public IPs

Public IP addresses provide external internet access to your virtual machines. Public IPs are allocated per network interface and are only available on standard (L3) networks.

Prerequisites

• The Tenant Administrator or Tenant Power User role

How Public IPs Work

• Each VM network interface on a standard network can have one public IP allocated
• Public IPs are assigned from a shared pool — you don't choose the specific address
• When released, the IP returns to the pool and becomes available for future allocations
• Custom (L2) networks do not support public IP allocation — because these networks operate as flat Layer 2 switches without any built-in routing, there is no gateway to direct inbound or outbound traffic for a dedicated IP

Allocate a Public IP

There are two ways to allocate a public IP address to a VM — at the time of creation, or on an existing VM after it has been deployed.

During VM Creation

Enable Allocate Public IP in the VM creation form to automatically allocate a public IP on the primary network interface.

After VM Creation

Allocate a public IP on any existing network interface connected to a standard network.

On the VM detail page, click Edit VM. In the Network Interfaces section, find the interface and click Allocate Public IP.

Release a Public IP

Remove the public IP from a network interface. The IP is returned to the pool.

On the VM detail page, click Edit VM. In the Network Interfaces section, click Release Public IP next to the interface.
