When is an IP address considered a Public IP address?
何時將 IP 地址視為公有 IP 地址？
Any IP address that is assigned to an instance or a service hosted in a VPC that can be accessed over the internet is considered a public IP address. Only public IPv4 addresses, including Elastic IP addresses (EIPs) and IPv6 GUA can be routable on the internet. To do so, you would need to first connect the VPC to the internet and then update the route table to make them reachable to/from the internet.
任何 IP 地址若指派給可透過網際網路存取之 VPC 中託管的執行個體或服務，都會被視為公有 IP 地址。只有公有 IPv4 地址，包括彈性 IP 地址 (EIP) 和 IPv6 GUA，可以在網際網路上路由。為此，您需要先將 VPC 連線至網際網路，然後更新路由表，讓其可從網際網路連線/從網際網路存取。
