What Is Elastic IP?

What Is Elastic IP?

Definition

An elastic IP address (EIP) is an IP address that can be directly accessed through the Internet. An EIP is a static public IP address. EIPs can be bound to or unbound from ECSs, BMSs, virtual IP addresses, or 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 to access the Internet, bind an EIP to the instance.

Network Scheme

Type I: Software is used to convert public and private IP addresses into each other.

Type II: Hardware firewall is used to convert public and private IP addresses into each other.

Functions

  • Binding an EIP

    You can apply for an independent EIP in the VPC. Public IP addresses can be bound to ECSs as required to allow ECSs to access the Internet. The binding and unbinding operations take effect immediately.

  • Setting the bandwidth limit

    When applying for an EIP, you can set the bandwidth limit for it.
