What Is Elastic IP?

The Elastic IP (EIP) service enables your cloud resources to communicate with the Internet using static public IP addresses and scalable bandwidths. If a resource has an EIP bound, it can directly access the Internet. If a resource only has a private IP address, it cannot directly access the Internet. EIPs can be bound to or unbound from ECSs, BMSs, virtual IP addresses, NAT gateways, or load balancers.

Each EIP can be bound to only one cloud resource.

EIP Types

EIPs can use dynamic BGP.

  • Dynamic BGP provides automatic failover and chooses the best path based on the real-time network conditions and preset policies.
  • When a fault occurs on a carrier's link, dynamic BGP will quickly select another path to take over services, ensuring service availability.

For more information about service availability, see Huawei Cloud Service Level Agreement.

Accessing EIP

You can access the EIP service through the management console or using HTTPS-based APIs.
  • Management console

    Log in to the management console, select Elastic IP from the console homepage, and then perform operations on EIP resources.

  • APIs

    If you need to integrate the EIP service provided by the cloud system into a third-party system for secondary development, you can use an API to access the EIP service. For details, see the Elastic IP API Reference.
