Elastic IP

Definition

  • A static IP address that can be reassigned to different resources to access resources over internet.
  • An EIP can be bound to or unbound from a virtual private cloud (VPC) resource, such as an elastic cloud server (ECS), bare metal server (BMS), virtual IP address, or elastic load balancer in a VPC subnet

Functions

  • Setting the bandwidth limit: When applying for an extranet IP address, you can set the bandwidth limit for it
  • Manually specifying an EIP or automatically allocating an EIP: When applying for an EIP, you can choose to manually specify one or automatically allocate one. When you choose to manually specify one, enter an idle IP address.

Application Scenarios

  • Using an EIP to Let a Cloud Server in a VPC Access the Extranet: To let a single cloud server in a VPC access the extranet, bind an EIP to it
