It is recommended to read a book such as a network administrator, which can be achieved by installing some kind of software.

Mobile phone inquiryCampus Network.

Turn on your phone and tap the "Settings" menu.

In the "Settings" window, tap on the "Wireless & Network" option.

In the "Wireless & Networking" window, click on the "Wi-Fi" option.

In the "Wi-Fi" window, click on the "Settings" option below.

In the Configure WLAN window, you can view the IP address assigned by the router to the phone.

For example, the campus network is a broadband multi-network that provides teaching, scientific research and comprehensive information services for teachers and students. First of all, the campus network should provide an advanced information-based teaching environment for school teaching and scientific research.

This requires that the campus network is a local area network with broadband, interactive functions and strong professionalism. Multi-teaching software development platform, multi-demonstration classroom, teacher preparation system, electronic reading room, teaching, examination database, etc., can all be run on the network.

If a school includes multiple professional disciplines (or departments), it is also possible to form multiple local area networks and connect them wired or wirelessly. Secondly, the campus network should have the functions of academic affairs, administration and general affairs management.

The IP address of the school falls under category A. Class A private IP addresses, in fact, are IP addresses of data centers, offices, homes, and schools, which are generally private IP address ranges. Because these addresses allow IT personnel within the organization to manage and assign their own addresses, and they can be repeated, which means that different school IP address blocks can be the same.

Partitioning of IP addresses.

The IP address is divided into five categories: 0-126, 128-191, 192-223, 224-239, 240-255, A, B, C, D, and E. Clients generally communicate with each other in the LAN, and generally use their own configured IP addresses to communicate with other clients in the LAN. DHCP can also be used to automatically obtain IP addresses.

There are five categories of IP addresses, Class A reserved for ** institutions, Class B for medium-sized companies, Class C for anyone who needs them, Class D for multicast, Class E for experiments, and the number of addresses that can be accommodated varies by class.

Internet cafes and cafes

Under the impact of the gradual popularization of home computers and mobile Internet terminals, Internet cafes have been put on the hat of "sunset industry", coupled with the dirty and messy industry image, internal war and vicious competition, etc., resulting in the overall economic benefits continue to decline, and many practitioners have chosen to withdraw. At the same time, many Internet cafes are also seeking to change to "Internet cafes" with smooth decoration and elegant environment.

Internet café, as the name suggests, is called to search coffee on the Internet, different from ordinary Internet cafes in the traditional sense, the original role and function is mainly to provide a comfortable and convenient Internet environment for business people. With the advancement of the times, Internet cafes have gradually become a new type of business that integrates both entertainment and leisure functions.

1. This depends on the DHCP server, generally there will be a time limit when the server is assigned to the computer IP address, we default to 8 days, but the situation will be different, some still have a few hours, if the address is in short supply, the time is relatively short. When the address usage time reaches 75% of the total time (or 85%, I can't remember the specifics), if the computer is on at that time, and you need to access the Internet, the computer will negotiate with the server to renew, if the last time has not been renewed, the server will assign this address to other applicants, and you may be assigned to another address when you connect to the Internet next time, and you may be assigned to the same address as you used before (if that address is not occupied). So not every time you log in, your IP address changes.

2. Check the IP addressClick on the icon of the two small computers in the lower right corner of the computer, select the "Support" tab, you can view the current IP address, and you can also view the subnet mask and gateway. You can also enter cmd in the operation to bring up the DOS window, and enter ipconfig all to view some information such as IP address, MAC address, DHCP server address, etc., which can be known according to the English display.

There are public IP addresses and subnet IP addresses. Every computer is different, just like an ID card.

Generally speaking, there will not be too many public IP addresses in Internet cafes, only one or two, and the public IP address is the IP that can be directly connected to the Internet and can be used on the Internet, but due to the scarcity of public IP addresses, it is impossible to configure a public IP address for each computer.

Ordinary computers in Internet cafes use private IP addresses, which means that such IPs can be used internally and freely. When a host with a private IP address wants to connect to the Internet, it has to go through a server with a public IP address for data**.

All private IP hosts in Internet cafes send and receive packets through one or more public IP addresses. So to be exact, there are many private IP addresses in Internet cafes, and there are only one or two public ones.

IP addresses are divided into internal IP addresses and external IP addresses

Intranet IP is like a student's student number No. 1, No. 2, No. 3, each class has an external IP is your class, you go outside, this is the only student in the ** class, the external IP is the only one, and the intranet IP is only the only one in the LAN, and all the intranet IPs all point to an external IPThe same Internet café has several lines, and there are several external network IPs

When a private IP address is connected to the network, the external IP address representing it is displayed in the networkThat is, the class mentioned earlier. Others also see the Internet IP, so the IP displayed by an Internet café is the same (here it is assumed that the Internet café has only one line - such as Netcom).

And every Internet café will have this IP segment, because IP leasing is very expensive, and the Internet café is 3000 a month with about 20MB traffic. Therefore, it is impossible for an Internet café to buy 100 IPs and distribute them to 100 computers, so he adopts the form of a local area network, that is, the intranet IP is allocated by the route to access the Internet.

Let's put it this way: Intranet IPs are the sons of extranet IPs.

It's different, it's different for each machine, it's usually like this, and the last digit is different.
