【文章內(nèi)容簡介】 復(fù)用 (PAT) 端口復(fù)用的特征是內(nèi)部多個私有地址通過不同的端口被映射到一個公網(wǎng)地址， Overloading, or Port Address Translation (PAT), maps multiple private IP addresses to a single public IP address. Multiple addresses can be mapped to a single address because each private address is tracked by a port number. 理想狀況下，一個單一的 IP地址可以使用的端口數(shù)為4000個。 Realistically, the number of ports that can be assigned a single IP address is around 4000.
