This article introduces how to allocate a public IP address to an instance, and focuses on the specific steps. The content of this article is compact, and I hope you can gain something from it.

Description

When calling this interface, you need to pay attention to:

Before assigning a public IP address, the instance must be in Running or Stopped status.

When a VPC type instance has been bound to an EIP, the public IP cannot be allocated.

An instance can only be assigned one public IP address. If the instance already has a public IP address, an AllocatedAlready error will be reported.

After restarting the instance (RebootInstance) or starting the instance (StartInstance), the new public IP address will take effect.

When the OperationLocks of a security-controlled instance is marked with "LockReason" : "security", a public IP address cannot be assigned.

In addition to assigning a public IP, you can also bind an elastic public IP (EIP) to an instance. See AssociateEipAddress for more details.
