# VNIC Attachment

A VNIC Attachment in Oracle Cloud Infrastructure links a virtual network interface card (VNIC) to a compute instance. It enables the instance to communicate on a specified subnet and defines network characteristics such as private IPs, security lists, and optional public IPs. This attachment is essential for providing network connectivity to the instance.
