# Load Balancer Network

The **Network** tab manages a load balancer's network attachments: its public IP, IPv6 address, and the VPCs it is connected to. The tab is available when the load balancer is Running, in Backend Connection Failure, or Backend Status Unavailable.

---

## Public IP

The Public IP section shows the address assigned to the load balancer, or **Not Assigned** for an internal load balancer.

- **Copy** — copy the IP to the clipboard.
- **Reserve** — if the address is not yet reserved and the load balancer is not Creating or Deleting, select **Click here** to reserve it. Reserving keeps the address so you can reuse it on a future load balancer. A **(Reserved)** badge appears once it is reserved.

For reserved-IP limits and pricing, see [Reserved IP](/docs/myaccount/network/reserve_ip/).

---

## IPv6

The IPv6 section shows the attached IPv6 address, or **Currently no IPv6 attached**.

- **Attach** — when no IPv6 is attached and the load balancer is not Creating or Deleting, select **Click here** to attach IPv6. Confirm in the "Are you sure you want to attach IPv6?" dialog.
- **Detach** — when IPv6 is attached, select **Click here** to detach it. Confirm in the "Are you sure you want to detach IPv6: \<address\> ?" dialog.
- **Copy** — copy the IPv6 address.

:::tip
Only attach IPv6 if your application and security group rules support it.

## Associated VPC

This section lists the VPCs attached to the load balancer, or **No VPC attached**.

The VPC table shows: **VPC Name**, **Subnet Name**, **IP**, **Network Mask** (CIDR), and an **Action** (detach).

### Attach a VPC

1. If no VPC is attached, select **Click here to attach**. Otherwise, select the **+** (Add VPC) control — shown when fewer than three VPCs are attached and the load balancer is not Creating or Deleting. The tooltip reads "Click here to attach another VPC."
2. Choose an available VPC, and optionally a subnet.
3. Confirm. On success the portal shows "VPC attached successfully" and the VPC appears in the Associated VPC list.

### Detach a VPC

1. Select **Detach** (the link-off icon) on the VPC row.
2. Confirm the action.
3. On success the portal shows "VPC detached successfully" and the VPC is removed from the list.

:::note
A load balancer can have at most **three** VPCs attached. An internal load balancer must keep at least one VPC. For VPCs and subnets, see [VPC](/docs/myaccount/network/vpc).
