To set the static IP address of a Windows Ethernet connection, you need to manually fill in the correct IP, subnet mask, default gateway, and DNS information. 1. Run ipconfig /all through the command prompt to obtain the current network parameters; 2. Select an IP address that does not conflict with DHCP (such as 192.168.1.100); 3. Open the network settings and enter the "Internet Protocol Version 4 (TCP/IPv4)" configuration interface; 4. Fill in the IP address, subnet mask (usually 255.255.255.0), the default gateway (such as 192.168.1.1) and the DNS server (you can use the gateway or public DNS such as 8.8.8.8); 5. Troubleshoot IP conflicts, firewall restrictions, driver exceptions, router restrictions, and DNS resolution failures when encountering problems. Static IP is suitable for scenarios where fixed IP is required such as building servers. It is recommended to use dynamic IP automatic acquisition method for daily Internet access.

Setting a static IP address is a common network configuration task in Windows Ethernet connections, and is suitable for scenarios where fixed IP is required, such as building a local server, remote access, or certain specific network environments. If you are looking for a way to do this correctly, the focus of this article is already very clear: the key to manually configure a static IP address is to fill in the correct IP, subnet mask, default gateway and DNS server information .

The following content will start from several common needs and help you complete the configuration process step by step.

How to find basic information about the current network

Before starting configuration, it is necessary to understand some basic parameters of your current network. This helps you choose a suitable static IP address and avoid conflicts with other devices.

You can view existing network information through the command prompt:

• Press Win R and enter cmd to enter
• Enter ipconfig /all and enter

You will see information similar to the following:

 IPv4 address. . . . . . . . . . . . . . : 192.168.1.5 (Preferred)
Subnet mask. . . . . . . . . . . . . : 255.255.255.0
Default gateway. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
DNS server. . . . . . . . . . . . . . : 192.168.1.1

This information can be used as a reference when setting up a static IP. It is recommended to select an IP address that does not conflict with the current DHCP allocation range (for example, change the last bit larger, such as 192.168.1.100).

How to set a static IP address in Windows

The way Windows system sets up static IPs is slightly different among different versions, but the overall process is similar. Here are the standard steps for Windows 10 and Windows 11:

1. Open Settings > Network and Internet > Status
2. Click "Change Adapter Options" or search directly for "Network and Sharing Center"
3. Click the Ethernet connection you are currently using
4. Click "Properties" > Double-click "Internet Protocol Version 4 (TCP/IPv4)"

Next, make the following configuration in the pop-up window:

• ? Select “Use the IP address below”
• Fill in the IP address you wish to use
• The subnet mask is usually 255.255.255.0 (based on the actual network situation)
• The default gateway is usually the address of your router, such as 192.168.1.1
• The DNS server can fill in the gateway address or use public DNS, such as 8.8.8.8 and 8.8.4.4

After confirming that, click "OK" and close all windows to take effect.

What to do if you encounter problems? Common errors and troubleshooting suggestions

If you cannot access the Internet or conflict occurs after the setup is completed, you can check it from the following aspects:

• ? IP address conflict : Make sure that the IP you set is not occupied by other devices. You can view the assigned IP list in the router management interface.
• ? Firewall or security software restrictions : Sometimes a third-party firewall will prevent the new network configuration from taking effect, try temporarily disabling it.
• ??Network adapter driver exception : Updating or reinstalling the network card driver can be operated using the device manager.
• ? Router restricts IP segments : Some enterprises or school networks have strict restrictions on IP, and you need to contact the administrator to obtain a legal address.
• ? DNS resolution failed : If you can ping the IP but can't open the web page, it may be a DNS problem. Please try changing the set.

When encountering problems, don’t rush to reset them, and check the most likely cause first.

A brief explanation of the difference between static IP and dynamic IP

Many people will ask, why do you sometimes need to manually set the IP instead of letting the system automatically obtain it?

• Dynamic IP (DHCP) : It is automatically allocated by the router, and each connection may be different. It is suitable for ordinary users and saves effort.
• Static IP (manual setting) : The IP address is fixed and suitable for situations where remote access, service building or port mapping is required.

If you are just surfing the Internet on a daily basis, it is enough to maintain the default automatic acquisition method; only switch to static IP when you really need it.

Basically all this is it. Setting up a static IP is not complicated, but you need to pay attention to details, especially avoiding IP conflicts and filling in the correct gateway information. As long as you follow the above steps, the configuration can generally be completed smoothly.
