EIP Overview

EIP

The Elastic IP (EIP) service enables you to use static public IP addresses and scalable bandwidths to connect your cloud resources to the Internet. 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 bound to only one cloud resource and they must be in the same region.

EIP Quotas

You can log in to the console to query your EIP quotas by referring to How Do I View My Quotas?.

If you want to increase your quota, see How Do I Apply for a Higher Quota?
  • 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 request for quota increase will be declined.
  • If you have increased the EIP quota but you have not used the quota for a long time, Huawei Cloud will reduce the quota to the default value.

EIP Advantages

  • Flexibility

    An EIP can be flexibly associated with or disassociated from the ECS, BMS, NAT gateway, load balancer, or virtual IP address. The bandwidth can be adjusted according to service changes.

  • Shared bandwidth

    EIPs can use shared bandwidth to lower bandwidth costs.

  • Immediate use

    EIP binding, unbinding, and bandwidth adjustments take effect immediately.

Notes and Constraints

  • If the used EIP bandwidth exceeds the purchased size or is attacked (usually by a DDoS attack), the EIP will be blocked but can still be bound or unbound.
  • EIPs cannot be transferred across accounts. That is, an EIP of account A cannot be transferred to account B.
