List of TCP and UDP port numbers
From Wikipedia, the free encyclopedia
This is a list of Internet socket port numbers used by protocols of the Transport Layer of the Internet Protocol Suite for the establishment of host-to-host connectivity.
Originally, these port numbers were used by the Network Control Program (NCP) and two ports were needed as transmission was done at half duplex. As Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) were adopted, only one port was needed. The even numbered ports were dropped. This is why some even numbers in the well-known port number range are unassigned. TCP and UDP port numbers are also used for the Stream Control Transmission Protocol (SCTP), and theDatagram Congestion Control Protocol (DCCP). SCTP and DCCP services usually use a port number that matches the service of the corresponding TCP or UDP implementation if they exist. The Internet Assigned Numbers Authority (IANA) is responsible for maintaining the official assignments of port numbers for specific uses.[1] However, many unofficial uses of both well-known and registered port numbers occur in practice.

Well-known ports[edit]
The port numbers in the range from 0 to 1023 are the well-known ports or system ports.[2] They are used by system processes that provide widely used types of network services. On Unix-like operating systems, a process must execute withsuperuser privileges to be able to bind a network socket to an IP address using one of the well-known ports.

Registered ports[edit]
 |
This article's use of external links may not follow Wikipedia's policies or guidelines. (October 2011) |
The range of port numbers from 1024 to 49151 are the registered ports. They are assigned by IANA for specific service upon application by a requesting entity.[1] On most systems, registered ports can be used by ordinary users.
This is an incomplete list of notable ports. See the Service Name and Transport Protocol Port Number Registry of IANA for the complete list of assigned ports.

Dynamic, private or ephemeral ports[edit]
The range 49152–65535 (215+214 to 216−1)—above the registered ports—contains dynamic or private ports that cannot be registered with IANA.[160] This range is used for custom or temporary purposes and for automatic allocation of ephemeral ports.

Node.js，简称Node，是一个开源且跨平台的JavaScript运行时环境，它允许在浏览器外运行JavaScript代码。Node.js于2009年由Ryan Dahl创立，旨在创建高性能的Web服务器和网络应用程序。它基于Google Chrome的V8 JavaScript引擎，可以在Windows、Linux、Unix、Mac OS X等操作系统上运行。 Node.js的特点之一是事件驱动和非阻塞I/O模型，这使得它非常适合处理大量并发连接，从而在构建实时应用程序如在线游戏、聊天应用以及实时通讯服务时表现卓越。此外，Node.js使用了模块化的架构，通过npm（Node package manager，Node包管理器）,社区成员可以共享和复用代码，极大地促进了Node.js生态系统的发展和扩张。 Node.js不仅用于服务器端开发。随着技术的发展，它也被用于构建工具链、开发桌面应用程序、物联网设备等。Node.js能够处理文件系统、操作数据库、处理网络请求等，因此，开发者可以用JavaScript编写全栈应用程序，这一点大大提高了开发效率和便捷性。 在实践中，许多大型企业和组织已经采用Node.js作为其Web应用程序的开发平台，如Netflix、PayPal和Walmart等。它们利用Node.js提高了应用性能，简化了开发流程，并且能更快地响应市场需求。
