Manage Network Interface (NIC)

The Network Interface tab on the Instance detail page lets you view and manage all NICs attached to the Instance. You can add a new NIC, create an Allowed Address Pair, and delete NICs that are no longer needed.

View the NIC List​

  1. Go to the Instance detail page.
  2. Select the Network Interface tab.

The list displays all NICs currently attached to the Instance:

Add a NIC​

An Instance supports a maximum of 10 NICs. You can add a NIC while the Instance is running or stopped.

  1. In the Network Interface tab, click Add NIC.
  2. Select the Subnet to attach the NIC to.
  3. Click Confirm. The IP address is assigned automatically from the Subnet's available range.

Add new NIC screen

Note: Each Instance supports a maximum of 10 NICs. If the Instance already has 10 NICs, the Add NIC option will not be available.

Per-NIC Operations​

Create Allowed Address Pair: Allow the NIC to receive traffic for an additional IP or MAC address beyond its assigned address. This feature is useful when running a Virtual IP (VIP) or configuring High Availability (HA) on the Instance.

Steps to create an Allowed Address Pair:

  1. Open the NIC's action menu.
  2. Select Add Allowed Address Pair.
  3. Enter the IP address (and optionally MAC) you want to allow.
  4. Click Confirm.

Delete Allowed Address Pair: Remove an Allowed Address Pair when it is no longer needed.

Delete NIC: Remove the NIC from the Instance.

Note: You cannot change the primary NIC.

Floating IP (Reference)​

A Floating IP is a public IP address that can be attached to or detached from an Instance to allow access from the internet. Floating IPs are managed in a separate module — not in the Network Interface tab.

See the full guide on allocating and attaching Floating IPs in the Manage Floating IP documentation.
