## 創建EIP ## 1. ECS公網IP 與eip 區別 序號 |功能| ECS公網IP | EIP :-: | :-: | :-: | :-: 1 |支持的網絡環境 |專有網絡 |專有網絡 經典網絡 2|是否能夠單獨持有|否|是 3|是否支持在ECS上的彈性插拔|否|是 4|ECS實例網卡上是否能看到該IP|經典網絡：能看到；專有網絡VPC：看不到|多EIP網卡可見模式下可見 2. 創建Eip EIP是一種NAT IP。它實際位于阿里云的公網網關上，通過NAT方式映射到了被綁定的云資源上。和云資源綁定后，云資源可以通過EIP與公網通信。 ● 可獨立持有的公網IP ● 可用于VPC中的 ECS實例、NAT網關、私網負載均衡SLB等產品 ● 可動態綁定和解綁 ● 可自帶IP地址上云，系統架構變動小，IP品牌信譽不變 ``` resource "alicloud_eip" "eip" { bandwidth = "10" # Internet charge type of the EIP, Valid values are PayByBandwidth, PayByTraffic.
