按端标语可分为3大类：
（1）公认端口（Well Known Ports）：从0到1023，它们紧密绑定（binding）于一些处事。凡是这些端口的通讯明确表白了某种处事的协议。例如：80端口实际上总是HTTP通讯。
（2）注册端口（Registered Ports）：从1024到49151。它们松散地绑定于一些处事。也就是说有许多处事绑定于这些端口，这些端口同样用于许多其它目的。例如：许多系统措置惩罚惩罚动态端口从1024摆布开始。
（3）动态和/或私有端口（Dynamic and/or Private Ports）：从49152到65535。理论上，不应为处事分配这些端口。实际上，机器凡是从1024起分配动态端口。但也有例外：SUN的RPC端口从32768开始。 0 凡是用于分析操纵系统。这一要领能够事情是因为在一些系统中“0”是无效端口，当你试图使用一种凡是的闭合端口连接它时将孕育产生差此外功效。一种范例的扫描：使用IP地点为0.0.0.0，设置ACK位并在以太网层广播。
