EIPs

Overview

The EIP service provides static public IP addresses and scalable bandwidths that enable your cloud resources to communicate with the Internet. You can easily bind an EIP to an ECS, BMS, NAT gateway, load balancer, or virtual IP address, enabling immediate Internet access. Learn more.

Advantages

• Ease of Use

  You can easily bind and unbind EIPs. You can also dynamically scale the bandwidth included in the EIP subscription to meet changing requirements.

• Flexible Billing

  EIPs are available on a pay-per-use (billed based on either bandwidth or traffic) and yearly/monthly basis.

• Shared Bandwidth

  You can configure multiple EIPs to share the same bandwidth and thereby streamline costs.

• Real-Time Adjustments

  All EIP binding or unbinding or bandwidth adjustments you make are effective immediately.

Usage Constraints

• Binding constraints
  • An EIP that is already bound to a cloud resource cannot be bound to another resource without being unbound from the current resource first. An EIP can be used immediately after being bound to a resource.
  • An EIP can be used by only one ECS at a time.
  • An EIP can only be bound to a resource in the same region.
  • EIPs that are frozen due to security reasons cannot be bound or unbound.
• If an EIP is billed on a pay-per-use basis, the maximum bandwidth is 2,000 Mbit/s. If you need more bandwidth, submit a service ticket or contact your account manager.
• Your request for a larger quota will only be approved if your account has valid orders and you are continuously using cloud resources. If you have released resources immediately after subscribing to them multiple times, your quota cannot be increased.
