This is a bit of a tricky question — the answer is both yes and no. More than one device can share the same external (public) IP address, but each device will have its own local (private) IP address. For example, your ISP (internet service provider) sets your home up with one external IP address. Since your router is what actually connects to the internet, the IP address is assigned to your router. Your router then assigns a local IP address to each device that is connected to the internet at a time. The external IP address is what is shared with the outside world. Your local IP address is not shared outside of your private home network.

這是個很難回答的問題 — 有也會不會。超過一台裝置可以使用相同的外部公開 IP 地址但每台裝置都有自己的本機私人 IP 地址。舉例來說您的 ISP 網路服務供應商為您設定了一組外部 IP 地址。由於您的路由器實際才是連線到網際網路的 IP 地址會先分配給您的路由器。然後您的路由器會為每組連線到網際網路的裝置分配一組本機 IP 地址。外部 IP 地址是會分享給外部世界的。您的本地 IP 地址並未分享給您的私人家庭網路。
