Overview

EIP

The Elastic IP (EIP) service enables your cloud resources to communicate with the Internet using static public IP addresses and scalable bandwidths. 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 different service requirements.

Each EIP can be used by only one cloud resource at a time. An EIP must be in the same region as the resource it is bound to. Cross-region EIP bounding is not supported.
