1.10 Verify IP parameters for Client OS (Windows, Mac OS, Linux)

Verifying IP Parameters for Client Operating Systems

Understanding how to verify IP parameters is crucial for troubleshooting network issues and ensuring proper connectivity. This section covers the basic steps to check IP configuration settings on various client operating systems: Windows, macOS, and Linux.

Windows

Using Command Prompt

1. Open Command Prompt:
Press Win + R, type cmd, and hit Enter.

2. Run the IP Configuration Command:
Type ipconfig and press Enter. This will display the current IP configuration for all network interfaces.

3. Interpret the Output:
Look for the following information:
- IP Address: The current IP address assigned to the network adapter.
- Subnet Mask: Defines the network portion of the IP address.
- Default Gateway: The IP address of the router or gateway used to reach other networks.
- DNS Servers: Addresses of the DNS servers used for resolving domain names.

Using Settings

1. Open Network & Internet Settings:
Go to Settings > Network & Internet.

2. View Network Properties:
Select Status and then click on Properties for the active network connection.

3. Check IP Details:
The IP address, subnet mask, and gateway can be found under the IP assignment section.

macOS

Using System Preferences

1. Open System Preferences:
Click the Apple logo in the top-left corner and select System Preferences.

2. Access Network Settings:
Click on Network.

3. Select the Network Interface:
Choose the active network interface (e.g., Wi-Fi or Ethernet) from the list on the left.

4. View IP Information:
Click on Advanced and go to the TCP/IP tab. Here, you’ll find the IP address, subnet mask, and router (gateway) information.

Using Terminal

1. Open Terminal:
Go to Applications > Utilities > Terminal.

2. Run the Network Setup Command:
Type ifconfig and press Enter. This will display detailed network information.

3. Interpret the Output:
Look for the section corresponding to the active interface (e.g., en0 for Ethernet or en1 for Wi-Fi). The IP address, subnet mask, and gateway information are listed here.

Linux

Using the Command Line

1. Open Terminal:
Access the terminal from your application menu or press Ctrl + Alt + T.

2. Run the IP Command:
Type ip a or ifconfig (if ifconfig is installed) and press Enter. This command displays network interface details.

3. Interpret the Output:
Look for the inet entry for each network interface. The IP address and subnet mask are shown here. The default gateway can be found using ip route or route -n.

Using Network Manager

1. Open Network Settings:
Go to Settings > Network.

2. Select the Network Interface:
Choose the network interface you want to inspect.

3. View Details:
Click on the gear icon or Details to see the IP address, subnet mask, and gateway.

Summary

Verifying IP parameters is a fundamental task for network troubleshooting and configuration. On Windows, you can use Command Prompt or the Network & Internet settings to view IP details. On macOS, System Preferences or Terminal commands provide the necessary information. On Linux, both terminal commands and graphical Network Manager can be used to check IP settings. Understanding how to access and interpret these settings helps ensure that your network connections are correctly configured and operational.
