Hi!

An elastic IP address (EIP) is a static IP address on the Internet and can be directly accessed through the Internet. You can bind EIPs to or unbind EIPs from resources in the subnet as required, including Elastic Cloud Servers (ECSs), Bare Metal Servers (BMSs), virtual IP addresses and elastic load balancers.

All IP addresses configured for instances in a local area network (LAN) on the private cloud are private IP addresses, which cannot be used for Internet access. To enable applications on an instance in a VPC to access the Internet, bind an EIP to the instance, which will allow the instance to access the Internet using a fixed public IP address.

Hello, friend!

What is EIP?

EIPs are static IP addresses designed for dynamic cloud computing. With an EIP, you can mask the instance faults by rapidly remapping the address to another instance in your account. EIP is associated with the tenant's account, instead of an instance. Before you release the EIP, it remains permanently associated with your account.
