What is a computer IP? Will the IP of the computer be changed once if the system is reinstalled?

The IP address, how to say it, is similar to a person's name, and it is used by China Mobile or China Unicom to assign Internet access.

He's using DHCP to automatically assign it, and if you're connected to the Internet, be aware of the fact that it's changing.

That is to say, you go down (disconnected) DHCP and give your address to someone else, so your address is not moving.

IP is like your ID number, each computer can only be assigned one, and you need an IP to access the Internet

The IP of the reinstalled system computer: the IP settings are assigned to the router set by themselves, if the router is automatically assigned, it may change, like a spot of adsl are dynamic IP, will change.

The IP address is the basis for data transmission in the IP network, which identifies a connection in the IP network, and a host can have multiple IP addresses.

The IP address is used to access the Internet, reconnect to the broadband and change the IP address.

To put it simply, if you're in the same place, then one computer has one IP address, just like your ID card, your home address, so when you reinstall your computer, as long as you're still in the same place, you're automatically assigned the same IP

IP is an identifier assigned to a computer device in the Internet, just like a person's ID card.

2. After reinstalling the system, the settings and data in the computer system disk will be cleared, and the IP address setting belongs to the system disk, so the IP address will also be not filled in by default, if you want to use a certain IP address, you need to set it again.

A: First of all, you have to determine what kind of method you use to surf the Internet, which can be roughly divided into 3 modes:

1. Use the Internet cable and fixed IP connection.

2. Use a network cable to connect to the router and automatically assign IP to connect to the Internet3. Use a wireless network to connect to the Internet.

If you use the first method, you write down the IP and manually fill it in after reinstalling the system; If it is the second way, don't move the network cable, click to automatically get the IP address after reinstalling the system; If it's the third way, it's simpler, just use the wireless network connection to go up Screenshots of the 1st and 2nd are attached below:

Computers on the LAN need to reset the IP, and the computers directly connected to the network will automatically get the IP address.
