Create and manage public IP

A public IP is a fixed address that can access the internet. A resource with a public IP attached can communicate externally through the internet gateway. The following describes how to create and manage public IPs in the VPC service.

Permission notice

• VPC role management follows IAM role-based access control (RBAC), and only users with the Project administrator (Admin) role can create and manage public IPs.
  
• You can check your role in KakaoCloud console > Profile (top right) > Organization role or Project role.
