You don't need to be a systems administrator to look after your home network. Many issues can be resolved by understanding a couple of concepts and using the right tools. Media Access Control address, or simply MAC address, is one of the most important.

Each device has its own MAC address, a 12-digit hexadecimal number assigned as a unique identifier. Finding the device's MAC address is useful for various cybersecurity and troubleshooting purposes.

You can identify the device - its maker and sometimes model, without having the device on hand or knowing its IP address. It's also useful for discovering unknown or unauthorized devices on your network. Whatever your reason, we'll help you find device name by MAC address in your network.

The Domain Name System (DNS) works like a massive address book for the internet. When you type a website name like “cometvpn.com”, DNS turns it into IP addresses that computers can read.

The Domain Name System has grown a lot over time. What started as a simple manual system has turned into smart, quick DNS servers that work automatically.

Now, services like Google Public DNS help make your internet faster and more secure. Let’s talk about that in more detail next.
