Configuring a static IP address on your macOS device can be crucial for various network-related tasks, such as setting up a server, ensuring consistent access to network resources, or improving network stability. Unlike dynamic IP addresses, which can change over time, a static IP address remains constant, making it easier to manage network configurations and troubleshoot connectivity issues.

In this article, we’ll walk you through the steps to configure a static IP address on your macOS device. This guide is designed to be straightforward and will include practical examples to help you understand the process.

Examples:

1. Using System Preferences:

   • Open System Preferences from the Apple menu.
   • Click on Network.
   • Select the network interface you want to configure (e.g., Wi-Fi or Ethernet).
   • Click the Advanced button.
   • Go to the TCP/IP tab.
   • Change the Configure IPv4 option to Manually.
   • Enter your desired IP address, subnet mask, and router address.
   • Click OK and then Apply to save the changes.

2. Using Terminal:

   • Open Terminal from the Applications > Utilities folder.
   • To find the current network service, you can use the following command:

     networksetup -listallnetworkservices

   • To set a static IP address, use the following command:

     sudo networksetup -setmanual "Wi-Fi" 192.168.1.100 255.255.255.0 192.168.1.1

     Replace "Wi-Fi" with the name of your network service, 192.168.1.100 with your desired IP address, 255.255.255.0 with your subnet mask, and 192.168.1.1 with your router address.

3. Verifying the Configuration:

   • To verify the static IP configuration, you can use the following command:

     ifconfig en0

     Replace en0 with the appropriate interface (e.g., en1 for Wi-Fi).
