How to Check IP Config on Mac

When it comes to configuring your internet settings on a Mac, understanding your MAC address is crucial. Your MAC (Media Access Control) address is a unique physical address assigned to each network adapter in a computer or mobile device.

To find your MAC address on a Mac, follow these steps:

1. Open the Settings app and navigate to General > About.

2. Scroll down to the Wi-Fi Address section, which lists your MAC address.

Your MAC address will be displayed in the format of ab-cd-ef-12-34-56, consisting of 48 bits or 12 hexadecimal characters separated by hyphens or colons.

Clearing DNS Cache on Mac and Linux

In addition to configuring your IP settings, clearing your DNS cache is an essential step to ensure you receive the correct IP mapping from DNS servers. Here's how to do it:

1. Open a terminal window.

2. Type in one of the following commands to clear the DNS cache:

* For macOS and Mac OS X versions: `sudo killall -HUP mDNSResponder`

* For Linux distributions, use the command specific to your distribution, such as:

+ Ubuntu: `sudo dscacheutil -flushcache`

+ Red Hat-based systems (e.g., Fedora): `sudo service bind9 restart`

+ Other Linux distributions: `sudo /etc/init.d/named restart` or `sudo systemctl restart named`

Clearing DNS Cache on Windows

To clear the DNS cache on a Windows system, follow these steps:

1. Press Ctrl + Alt + T to open the Command Prompt.

2. Right-click on the Command Prompt icon and select 'Run as administrator.'

3. Type in one of the following commands to clear the DNS cache:

* `ipconfig /flushdns`

* `netsh dns flush`

Clearing your DNS cache is a simple process that can help resolve DNS-related issues. Whether you're using a Mac, Linux, or Windows system, the steps above will guide you through the process of clearing your DNS cache. Remember to restart your terminal window or Command Prompt after executing the command to ensure the changes take effect.
