课程名称：IP地址与子网划分 - 简单易懂！ 课程概述：本课程通过实际案例和绘图板（彩色笔）进行授课，采用互动式教学，不使用幻灯片，让学员们可以实际看到如何实施IP地址和子网的技巧。IP地址（互联网协议地址）是计算机在互联网上定位的方式，用于识别网络中的设备。它通过一系列数字告诉计算机信息的发送与接收位置。 课程内容包括： 1. IP地址的分类： - Class A：支持16,777,216个主机设备 - Class B：支持65,536个主机设备 - Class C：仅允许254个主机设备 2. IP地址计算：课程将讲解如何使用IPv4地址方案，通过结合网络地址和主机地址生成32位数字，以计算IP地址的各个部分。 3. ISP提供IP地址的原因：作为互联网服务提供商（ISP），如Verizon或AT&T，需追踪网络流量以便计费，同时管理客户的IP地址以保证资源访问控制。 4. 子网的概念：子网是IP地址空间的逻辑划分，包含私有地址与公共地址，子网掩码定义了IP地址中网络地址与主机地址的划分。 讲师Atul Sharma拥有超过11年的行业经验，对网络技术有深入的理解并通过在线视频培训了数百名IT学生。他提供个别和小组在线培训，曾在多家顶尖公司工作，致力于帮助学生在CCNA面试中取得成功。 本课程旨在通过互动学习和实践应用，帮助学员掌握IP地址与子网划分的基础知识和技能。
This course is taught using real world examples and a Blackboard with Color Pens. This class will not use slides to teach, it is a very interactive class with actual examples and ways to implement them. You will actually see how to implement IP addresses and subnets.Ip addressingIp addressing, also known as internet protocol addressing, is the way that a computer is located on the internet. It is a system of numbers used to identify a device on a network. This is what is used to tell the computer where to send information it is sending or receiving from the internet.Class A allows a network of 16,777,216 host devices.Class B allows a network of 65,536 host devices.Class C permits only 254 host devices.How do we calculate IP addressing?IPv4 is the addressing scheme we use today. It's the one that most of us learned in school. You probably know that an IP address is made up of four numbers between 0 and 255. But how do we calculate those numbers? It all starts with a 32-bit number created by the combination of a network address and a host address.Why ISP provides an Ip address ?Imagine you are an internet service provider (ISP) like Verizon or AT & T, and you offer internet access to your customers. You need a way to track the internet traffic that goes in and out of your network so that you can bill your customers for their internet usage. You also want to make sure that your customers are only able to access the internet resources that you approve. This means you need to have some sort of system for managing the IP addresses (a unique number that is assigned to each device on a network and used for routing information) that are being used by your customers.What is a subnet?A subnet is a particular logical division of an IP address space. The IP address space is made up of private and public addresses, with the private addresses being used on private intranets and the public addresses being used for the Internet. The subnet mask defines which part of an IP address is used for the network address and which part is used for the host address. The remaining parts of the IP address are used for defining the subnet.Atul Sharma who worked with many TOP companies took one online workshop few days back. These are the videos of that workshop.
