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.
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.
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
- 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."
- Choose an available VPC, and optionally a subnet.
- Confirm. On success the portal shows "VPC attached successfully" and the VPC appears in the Associated VPC list.
Detach a VPC
- Select Detach (the link-off icon) on the VPC row.
- Confirm the action.
- On success the portal shows "VPC detached successfully" and the VPC is removed from the list.
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.
