This article mainly explains "TC/ip protocol introduction and configuration method". The content of the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn "TC/ip protocol introduction and configuration method".

TCP/IP protocol family: is the most widely used set of communication protocols

Including a large number of standard protocols in Internet applications

Support communication across network architectures and operating system platforms

Three elements of communication between hosts:

IP address (address): identification of the network address of each node in the network

Subnet mask (subnet mask): distinguishes between network bits and host bits to determine whether the IP address belongs to the same network

IP routing (router): a path choice for data communication

IP address composition (dotted decimal)

A total of 32 bits binary bits: network bits host bits

11000000.10101000.00000001.00000000 / 11111111.11111111.11111111.00000000

Converted to 4 decimal numbers, represented by. Separation: 192.168.1.0 Universe 24 (255.255.255.0)

IP address version: total number of ipv4 32 to the power of 2

The total number of ipv6 to the power of 128,

Classification of IP addresses

Category A: 001Mui 127. Lord. Lord. Master = "Subnet mask: 255.0.0.0 (where 127.0.0.0 is the loopback address)

Class B: 128Mui PMI 191. The net. Lord. Master = > Subnet Mask 255.255.0.0

Category C: 192 murmur223. The net. The net. Master = "Subnet Mask: 255.255.255.0

Category d: 234Mutual 239 Multicast address

Category e: 240murmur254 scientific research address

VPC address: (lan address)

ARV 10.0.0.0-10.255.255.255Universe 8 (where 10.0.0.0pacer 8 represents the network address: 10.255.255.255pl8 represents the broadcast address)

BRV 172.16.0.0-172.31.255.255Universe 16

192.168.0.0-192.168.255.255ax 24

Tip: private addresses cannot be transmitted over the public network

Public address: the rest is leased temporary address to pay for NIC (public address can also be used as host address)

Loopback address: special for testing native TCP/ip (127.0.0.1-127.0.0.254)

II. Configuration of IP address

Open network and Internet settings-configure network adapter-select network card to be configured-right-click Internet protocol version 4-manually configure IP address (automatically obtain IP address, DHCP server is required)

Win+r enter cmd Open Command prompt enter ipconfig / all to view the local IP address

DNS: domain name resolution protocol (resolving domain names to IP addresses) is mainly used to access web pages.

IP backup configuration: give priority to using DHCP. If something goes wrong, start the backup configuration.

Test network connectivity (two hosts are on the same network, or two networks are directly connected)

Win+r cmd ping command (icmp protocol)

(firewall settings)

Self-test network tcp/ip drives ping 127s. 0.0.0 or your own IP address loopback address

Third, configure the network environment of the workgroup

Working group: equal status, decentralized management, no centralized management of the network work environment

Default workgroup: workgroup

Computer name: unique in the same network

Working group name: changed to the same name on the same network, automatically classified as the consent working group

Domain network: a network environment with status division, controller and centralized management

Fourth, Internet access

Network Service provider (ISP): telecom; Mobile; Unicom

Service provider provides temporary IP address, dns server address

Access to the network:

1 Optical fiber-optical cat-router-computer (terminal)

2 dial-up Internet access to create pppoe dial-up Internet access
