How to carry out IP address analysis and application, in view of this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible method.

1. IP address

1. IPV4 is made up of 32-bit binary numbers

2. The IP address consists of two parts: network bits and host bits.

3. Classification of IP addresses:

Category range network bits and host bits

A 1-126 network + master

B 128-191 net + Network + Master + Master

C 192-223 network + master

D 224-239 Multicast address

E 240-254 Scientific Research

2. Private network address

A 10.0.0.09 10.255.255.255

B 172Jing 16.0.05172.31.255.255

C 192.168.0.05192.168.255.255

3. Subnet mask

The subnet mask is used to distinguish between network bits and host bits of IP addresses.

The network bits are represented by consecutive ones, and the host bits are represented by consecutive zeros.

172.16.100.100 255.255.0.0

192.168.180.180 255.255.255.0

10.22.22.22 255.0.0.0

4. Network ID (network number)

The IP of the network bits is unchanged, and the host bits are represented by consecutive zeros.

172.16.1.1 172.16.0.0

10.1.1.1 10.0.0.0

192.168.1.2 192.168.0.0

V. Network testing tools

1 、 ipconfig

2 、 ipconfig / all

3 、 ping

4 、 traceroute

VI. Preparatory work for equipment configuration

1. Configure the console call-back time (idle for a period of time and return to the original interface)

Global mode: line console 0

Exec-timeout 0 0 the former is minutes and the latter is seconds

0 means never time out

2. Configure the console to interrupt input processing (input log synchronization)

Global mode: line console 0

Logging synchronous

3. Disable DNS query

Global mode: no ip domain-lookup

So much for the answers to the questions on how to analyze and apply IP addresses. I hope the above content can be of some help to you. If you still have a lot of doubts to solve, you can follow the industry information channel to learn more about it.
