我们知道，TCP/UDP的端口号有三个种类：Well Known Ports（公用端口）,
th Registered Ports（注册端口）, 和Dynamic/ Private Ports（动态/私有端口）.
公用端口从0 到 1023，所以，我们的私用端口号不应该使用这个区间内的端口，除非你向IANA注册了。注册的流程参见文档资料[RFC4340]， 见章节19.9.
注册端口号从 1024 到49151，所以，你也不应该使用这其中的端口，除非你的向IANA注册了。注册的流程参见文档资料[RFC4340]，见 章节19.9.
而我们的动态的或私用端口是从 49152 到 65535，你可以使用这其中的端口，这样，你的程序就不会和别的公用的程序冲突了。
下面是所有的公用和注册端口的列表，这个列表来自下面的这个网站，这个列表最新的更新日期是：2009-09-25。（该列表很长，你需要耐心一点）
![]( "更多...")
公用端口号
公用端口号由IANA指定并只能被系统或系统管理员账号使用。这些端口被用于 TCP [RFC793]。下面是其端口列表：asdffasdfasdfas
