What Are EIPs?
An EIP is a public IP address that can be accessed directly over the Internet. An EIP consists of a public IP address and some amount of public network egress bandwidth. EIPs can be bound to or unbound from ECSs, BMSs, virtual IP addresses, NAT gateways, and load balancers.
Each EIP can be used by only one cloud resource at a time.
EIPs can be flexibly bound to or unbound from ECSs, BMSs, NAT gateways, load balancers, or virtual IP addresses. The bandwidth can be adjusted according to service changes.
Pay-per-use (based on bandwidth usage or amount of traffic) and yearly/monthly billing modes are available. EIPs can use shared bandwidth to lower bandwidth costs. The yearly/monthly billing mode is more cost-effective for you.
- Easy to use
EIP binding, unbinding, and bandwidth adjustments take effect immediately.
- Management console
You can use the console to perform operations on EIP resources directly. To access the EIP service, log in to the management console and select Elastic IP from the console homepage.
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.
