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 to dynamic BGP.

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.

IPv6 EIP Overview

Shared Bandwidth

All ECSs, BMSs, and load balancers can share the same bandwidth if they reside in the same region and have EIPs bound.

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