How to Mask Ip Address on Windows 10
Every device on a network has a unique address called its IP address, and this helps identify the device and enables other devices to communicate with it.
For example, when you type a URL in your browser, such as www.espn.com , what essentially happens is that your device sends the URL to a Domain Naming Server that translates this URL to an IP address. The request is then routed to the device or server with this IP address. If the server responds, the information you requested is sent back to your device.
In this communication, the server and your device must know to whom it must send a message, and this is where IP addresses come in handy.
What is an IP Address?
The word "IP" stands for Internet Protocol, and this address identifies a device including its location, thereby helping devices communicate with each other.
There are four types of IP addresses, namely, public, private, static, and dynamic. Private IP addresses are often used within a network. In contrast, a public IP address is used outside a network to enable other network devices to identify and communicate with the said device.
Static and dynamic IP addresses, on the other hand, signify permanence. Static IP addresses never change, which means the device will have the same IP address as it was created manually. On the other hand, dynamic IP addresses frequently change as they are assigned by a Dynamic Host Configuration Protocol (DHCP) server.
Further, IPs can be 32-bit or 128-bit. The former, called IPv4, is currently in use and is slowly being replaced by IPv6 (128-bit)
You can use a combination of these IP address types to configure devices within a network. However, regardless of how you configure these IP addresses, they come in handy to recognize devices, troubleshoot network errors, identify potential attacks or intruders, know the location or origin of content like emails or videos, and more.
These IP addresses can be masked through Virtual Public Networks (VPNs), and in some rare cases, they can be lost. In such situations, how do you find the IP address?
One option is to use the MAC address of a device to identify its corresponding IP address. But before that, what is a MAC address, and what's its connection with the device's IP address?
What is a MAC Address?
A Media Access Control (MAC) address is the physical address of a device, and it is built into it at the time of manufacture, so this address cannot be changed throughout the life of the device. It is mainly used in devices that follow the IEEE specifications, such as Bluetooth, Wi-Fi, and Ethernet, though it can be extended to other technologies.
MAC address comprises 48 bits, and this value is embedded into the Network Interface Card. These 48 bits are represented as a 12-digit hexadecimal number or a six-byte binary number separated by colons. The first three octets or six digits represent the manufacturer. They are called the Organizational Unique Identifier, while the last three octets or six digits represent the Network interface Controller assigned by the manufacturer.
A sample MAC address is CC:46:D6:00:b3:81. The first six digits tell you that this is a Cisco device, while the last six digits are the NIC number. Note that the colon is replaced by a period in Cisco systems.
To find the MAC address of a device, simply type "ipconfig/all" in the command prompt of your Windows device. You'll get a ton of information, so scroll through them to find the MAC address of the device.
If you have a Unix or Linux system, type "ip address show," For macOS, use the command – "TCP/IP Control Panel".
All these commands will give extensive information about the device, and you'll have to look through them for the MAC address.
As you may have guessed, the MAC address can be used to identify the IP address. But before we get into how you can use a MAC address to find an IP address, let's look at a way to convert the different formats.
Address Resolution Protocol (ARP)
In short, Address Resolution Protocol, or ARP, is a communication protocol that connects an IP address of a device to its MAC address. Typically, this protocol sends a request to all machines within the LAN to check which device uses an IP address. When a device responds to this request, the ARP maps its MAC address with the IP address in its table.
ARP works in layers 2 and 3 of the OSI model, as MAC addresses are present in layer two and IP addresses are in layer three, and the ARP table is the critical link that connects the two addresses, as it converts the 48-bit address of MAC to the 32-bit IP address.
How to Find an IP Address Using a MAC Address?
Here is a step-by-step guide to find the IP address of a device using its MAC address.
- Open the command prompt
- Type "arp" to see the different options that you can use with it.
- Use "arp -a", as this parameter lists all the MAC addresses and their corresponding IP addresses.
- Scroll through the MAC address list until you find the MAC address you want an associated IP address.
- Now, find the IP address mapped with the MAC address you want.
Thus, this is how you can find an IP address using a device's MAC address.
As you can see, it is not the most intuitive way to find the information you want and undoubtedly, requires a certain level of technical expertise in handling Command prompt and the related commands. It also needs a thorough understanding of the ARP protocol and how to use it to find the information you want.
An easier option is to use third-party tools, as all the complex processes are relegated to the background, and all that you have to do is enter the MAC address on a web interface. In turn, you get the associated IP address on the screen, so you don't have to worry about remembering commands or their meaning.
Furthermore, these tools give you more information and enable you to get a comprehensive idea of your device's health and performance.
Since these third-party tools are user-friendly and comprehensive, let's take a look at the popular ones.

Conclusion
To recap, an IP address is a unique address that helps identify a device online so that other devices can communicate with it. However, it may be unable to find these IP addresses, especially in a dynamic environment. In such cases, your best bet is to use a MAC address to identify it.
A MAC address is the physical address, and the ARP protocol is responsible for mapping each device's MAC and IP address. So, querying this ARP protocol and its table can help identify the IP address associated with a MAC address.
This manual process is time-consuming and effort-centric, and a more straightforward option would be to use third-party tools. The added benefit is that these tools give additional information that helps you stay on top of your device's health and performance.
