What Are EIPs?

An EIP is a static public IP address that can be accessed over the Internet. Bandwidth will be assigned together with an EIP. EIPs can be bound to or unbound from ECSs, BMSs, virtual IP addresses, NAT gateways, or load balancers. Various billing modes are provided to meet diverse service requirements.

Each EIP can be used by only one cloud resource at a time.
