课程名称：精通IPv4地址与子网划分（作者：Arash Deljoo） 课程概述： IPv4（互联网协议第四版）是由互联网工程任务组（IETF）于1982年引入的标准，负责路由互联网流量及其他分组交换网络。尽管IPv4的32位地址空间存在局限性，但它仍是目前使用最广泛的协议版本。可用的独特地址数量不足43亿，随着时间的推移，这一数量很快就开始减少。通过多年的巧妙改进，IPv4地址池在2011年之前没有枯竭。 互联网协议地址是连接到网络的设备的唯一标识符，使设备能够相互发现和通信。最初需要IP地址的主要设备类型包括计算机、服务器、路由器和打印机等网络设备。然而，随着物联网的发展，手机、电视、冰箱、汽车、灯泡等任何能够通过网络接收或交换信息的设备如今也需要IP地址。 IPv4地址由四组八位二进制数字组成，数字间用小数点分隔。尽管可以使用任何数字系统表示独特的32位数字，但IP地址通常采用点十进制表示法。 这个课程帮助学员深入理解IPv4协议的基础、应用及其重要性，以便更好地管理和分配网络资源。
Internet Protocol version 4 (IPv4) is the fourth version of the standard that routes Internet traffic and other packet-switched networks introduced in 1982 by the Internet Engineering Task Force (IETF). IPv4 is the most widely used version of the protocol despite the limitations of its 32-bit address space. With slightly less than 4.3 billion available unique addresses, the available number of addresses quickly began to run out. With some clever ingenuity over the years that extended the life of the protocol, the pool of available addresses didn't dry up until 2011.An Internet Protocol address is a unique identifier for devices connected to a network. The unique identifier makes it possible for devices to find and communicate with each other. Initially, the main types of devices that required an IP address included network devices, such as computers, servers, routers, and printers. However, with the Internet of Things, the list includes cell phones, televisions, refrigerators, automobiles, light bulbs, or anything else capable of receiving or exchanging information over a network.An IPv4 address is a series of four eight-bit binary numbers separated by a decimal point. Although you may use any numbering system to represent a unique 32-bit number, most commonly you see IP addresses expressed in dot-decimal notation.
