How to configure a static IP address
Jul 28, 2025 am 01:22 AM
Configuring a static IP address requires operation according to the operating system and network environment. Common steps are as follows: 1. Windows settings: Enter the "Network and Sharing Center" through the "Control Panel", change the adapter settings, select the currently connected network, and set the IPv4 IP, subnet mask, gateway and DNS; 2. Linux (such as Ubuntu) settings: Edit the /etc/netplan/ configuration file, specify the address, gateway and DNS and apply it; 3. Router settings: Log in to the background to bind the MAC address and IP to avoid conflicts. Fill in the parameters correctly and ensuring the information is accurate can avoid connection problems.
It is actually not difficult to configure a static IP address, but it needs to operate according to your operating system and network environment. If you are dialing up at home or in a small office, DHCP will usually automatically assign IP addresses. However, in some scenarios, such as building a server, remote access or specific device management, it is necessary to manually set a fixed IP address.
Here are some common methods for configuring static IP in systems that are suitable for most users' needs.
How to set up a static IP on Windows system
Setting up a static IP on Windows is intuitive and suitable for most home and small office users:
- Open Control Panel > Network and Internet > Network and Sharing Center
- Click "Change Adapter Settings" on the left
- Right-click the currently connected network (such as Ethernet or Wi-Fi) > Properties > Double-click "Internet Protocol Version 4 (TCP/IPv4)"
- Select "Use the IP address below"
- Fill in the IP address, subnet mask, default gateway, and DNS server address
For example:
Assuming your router IP is 192.168.1.1 , you can set the computer IP to 192.168.1.100 , the subnet mask is usually 255.255.255.0 , and the DNS can be filled in 8.8.8.8 or use the router address directly.
Remember to confirm that the IP you filled in does not conflict with other devices, otherwise it will cause the Internet to be unable to be connected.
How to set a fixed IP on Linux system
The configuration method of Linux is a little more complicated, and there are slight differences between different distributions. Here we take Ubuntu as an example:
- Edit network configuration files, usually
/etc/netplan/*.yamlor throughnmclitools - Modify it to the following format (the specific path may be different):
network: version: 2 ethernets: enp0s3: dhcp4: no addresses: - 192.168.1.101/24 gateway4: 192.168.1.1 nameservers: addresses: - 8.8.8.8 - After saving, execute
sudo netplan applyto take effect
Note: Different Linux distributions are configured differently. For example, CentOS uses nmcli or edits /etc/sysconfig/network-scripts/ifcfg-* files.
This IP must be reserved in the router
Even if you set up a static IP on the device, conflicts may occur if the router's DHCP pool is also assigned the same address. To avoid this, you can do an "IP address reservation" or "DHCP static allocation" in the router background:
- Log in to the router background (usually the browser input
192.168.1.1) - Find the DHCP settings or client list
- Bind a specific IP to the MAC address of the device you want to fix the IP
This ensures that even if the device is occasionally restarted, there is no duplicate IP assigned by DHCP.
Basically that's it. As long as you understand your network structure, choose the right parameters, and set up a static IP, it is not complicated, but it is easy to be unable to access the Internet due to negligence in details, especially the subnet mask and gateway are easily filled incorrectly. When encountering problems, you can first restore DHCP to see if it is normal, and then gradually check.
