How to configure a static IP address on Windows

Assigning a static IP address in Windows ensures a permanent address for stable communication on the network. This approach removes the possibility of changing addresses assigned by a DHCP server and simplifies remote access to critical devices, such as servers or printers. It provides consistent connectivity for administrative tasks and maintenance.

A static IP is beneficial for remote desktop connections, file servers, and network-attached storage (NAS) that need uninterrupted access. This method mitigates IP conflicts because addresses do not change dynamically. It also helps administrators monitor and manage network resources more efficiently.

Collecting relevant network details such as the default gateway, subnet mask, and DNS server addresses is essential for proper configuration. These parameters align the assigned IP with existing network settings and minimize the risk of conflicts with the router’s dynamic range. Selecting an IP address outside the DHCP pool supports reliable network performance.

1. Open the Network Connections settings by pressing <Windows + X> and selecting Network Connections.
2. Choose Ethernet or Wi-Fi, depending on your connection, and click Change adapter options.
3. Right-click the network adapter and select Properties.
4. Double-click Internet Protocol Version 4 (TCP/IPv4) to open its properties.
5. Select Use the following IP address.

   Ensure the static IP address you assign is outside the range allocated by the router’s DHCP server to avoid IP conflicts.

6. Enter the static IP address, subnet mask, and default gateway.

   IP Address: 192.168.1.100  
   Subnet Mask: 255.255.255.0  
   Default Gateway: 192.168.1.1

   These values must match your network's configuration. The IP address must be within the same network range but outside the DHCP range.

7. Enter the Preferred DNS server and Alternate DNS server if needed.

   Preferred DNS: 8.8.8.8  
   Alternate DNS: 8.8.4.4

   Use your ISP's DNS servers or a public DNS like Google DNS (8.8.8.8) or Cloudflare DNS (1.1.1.1).

8. Click OK to save the changes and close the settings.
9. Open Command Prompt to verify the new IP.

   ipconfig
   Ethernet adapter Ethernet:
   
      Connection-specific DNS Suffix  . : 
      IPv4 Address. . . . . . . . . . . : 192.168.1.100
      Subnet Mask . . . . . . . . . . . : 255.255.255.0
      Default Gateway . . . . . . . . . : 192.168.1.1

   Use ipconfig to check the network details and confirm the static IP configuration is applied.
