Computer IP address modification tutorial

The Importance of IP Addresses

To gain insight into how to change your computer's IP address, you first need to understand the importance of an IP address.An IP address is like the address of a house, it is used to identify your computer's location in the network. Through the IP address, the network can accurately find your computer and deliver data to your computer. Therefore, the setting of IP address is directly related to your smooth and safety on the network.

View current IP address

Before we can change the IP address, we need to check the current IP address. This step is quite simple, in Windows system, just open the command prompt (CMD), and then enter the command "ipconfig", enter to execute. In Mac system, open the terminal and enter the command "ifconfig" to check the current IP address.
"`bash
ipconfig
“`
maybe
"`bash
ifconfig
“`
In the information displayed, you will find a line like "IPv4 address" or "inet address" followed by a string of numbers, which is your current IP address.

Steps to change the IP address

Next, we will introduce how to change the IP address in detail. First of all, you need to enter the network settings interface, in Windows system, you can find the network and Internet settings in the Control Panel, and then click "Change adapter settings". In Mac system, you can find Network Settings in System Preferences.

Steps for modification under Windows system:

1. Locate the network adapter you are currently using, typically Ethernet or Wi-Fi.
2. Right-click the adapter and select Properties.
3. In the pop-up window, find the "Internet Protocol version 4 (TCP/IPv4)" or "TCP/IP v4" option, double-click to open.
4. In the new pop-up window, select "Use the following IP address" and fill in the IP address, subnet mask and default gateway you want to set.
5. Click OK to save the settings and close all windows.

Steps for modification under Mac system:

1. Open System Preferences and click Network.
2. In the list on the left, select the type of network connection you are currently using, such as Wi-Fi or Ethernet.

5. Click OK to save the settings and close all windows.

Check if the modification was successful

After modifying the IP address, we still need to check if the modification has been successful. Under Windows system, you can open the command prompt again and enter the command "ipconfig" to check if the current IP address has been changed. Under Mac system, you can open the terminal again and enter the command "ifconfig" to check.
"`bash
ipconfig
“`
maybe
"`bash
ifconfig
“`
Make sure that the newly set IP address has taken effect so that your computer can use the new IP address to connect to the network.
