EIP Functions

EIP

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

You can assign EIPs, bind them to or unbind them from cloud resources, release EIPs, modify EIP bandwidth, and upgrade static BGP EIPs to dynamic BGP EIPs.

Figure 1 Connecting to the Internet using an EIP

For details, see Assigning an EIP.

IPv6 EIP

Both IPv4 and IPv6 EIPs are available. You can assign an IPv6 EIP or map an existing IPv4 EIP to an IPv6 EIP.

After the IPv6 EIP function is enabled, you will obtain both an IPv4 EIP and its corresponding IPv6 EIP. External IPv6 addresses can access cloud resources through this IPv6 EIP.

For details, see IPv6 EIP Overview.

EIP Pool

An EIP pool helps you manage a large number of EIPs and assigns EIPs with dynamic BGP routing, ensuring network stability and excellent user experience.

You can purchase and modify EIP pools.

For details, see EIP Pool Overview.

Shared Bandwidth

A shared bandwidth allows multiple EIPs to share the same bandwidth. The EIPs of all ECSs, BMSs, and load balancers can share the same bandwidth if they are in the same region.

You can assign, modify, delete a shared bandwidth, add EIPs to a shared bandwidth, and remove EIPs from a shared bandwidth.

You can enable and disable QoS.

For details, see Shared Bandwidth Overview.

Shared Data Package

A shared data package provides a quota for data usage. Such packages are cost-effective and easy to use. Shared data packages take effect immediately after your purchase. If you have pay-per-use EIPs billed by traffic in a region and buy a shared data package in the same region, the EIPs will use the shared data package. After the package quota is used up or the package expires, the EIPs will continue to be billed on a pay-per-use basis.
