Welcome to the world of cyber security! In this day and age, it is important to know about the different ways hackers can enter your network. One way is by using a fake MAC address to gain access. But don’t worry, there is a solution to this problem. In this article, we will be discussing the steps to get IP from MAC address. This will help you avoid any security threats and keep your network secure.
Steps to Follow:
Step 1: Identify the MAC Address
The first step in getting the IP address from a MAC address is to identify the MAC address itself. A MAC address is a unique identifier assigned to a network adapter by the manufacturer. This identifier is used by the network to identify each device on the network. To identify the MAC address, you will need to go to the settings of the device you want to locate the IP address for.
Step 2: Open Command Prompt
Once you have identified the MAC address, the next step is to open Command Prompt. This is a command-line interface used for executing commands. To open it, click on the start menu, type ‘cmd’ and press enter.
Step 3: Type ARP Command
Now that you have opened Command Prompt, the next step is to type in the ARP command. This command is used to display and modify the ARP cache. The ARP cache is a table that maps IP addresses to MAC addresses. To type in the command, enter ‘arp -a’ and press enter.
Step 4: Identify the Physical Address
Once you have entered the ARP command, you will see a list of IP addresses and their corresponding MAC addresses. Look for the IP address of the device you are trying to locate the IP address for. Then, identify the Physical Address which is the MAC address.
Step 5: Write Down the MAC Address
Write down the MAC address for future reference. You will need it in the next steps.
Step 6: Use the Command ‘Ping -a’
Now that you have the MAC address written down, the next step is to use the command ‘ping -a’ followed by the MAC address. This command is used to locate the IP address of a device.
Step 7: Identify the IP Address
Once you have entered the ‘ping -a’ command followed by the MAC address, you will see the IP address of the device in question.
Step 8: Record the IP Address
Write down the IP address for future reference. This is the IP address assigned to the device with the MAC address you just located.
Step 9: Verify the IP Address
Once you have located the IP address, you should verify that it is correct. You can do this by using the ‘ping’ command followed by the IP address you just located. If the ping is successful, it means that the IP address is correct.
Step 10: Use a Port Scanner
If you want to verify that the device with the IP address you just located is actually the device you are looking for, you can use a port scanner. A port scanner is a tool used to scan a network to see which ports are open on each device. If the device you are looking for has a specific port open, you will know that it is the right device.
Step 11: Note the Open Ports
Once you have used the port scanner, note which ports are open on the device you are looking for. This will help you determine if it is the correct device.
Step 12: Use the IP Address to Connect
Now that you have located the IP address of the device you are looking for and have verified that it is the correct device, you can use the IP address to connect to the device. You can do this by using remote desktop or any other tool that allows you to connect to a device on the network.
Now that you have followed the above steps, you should have successfully located the IP address of the device you were looking for. The ARP command is crucial in this process as it allows you to display and modify the ARP cache. The ARP cache is a table that maps IP addresses to MAC addresses. By using the ‘ping -a’ command followed by the MAC address, you are able to locate the IP address of the device. The port scanner allows you to verify that the device with the IP address is actually the device you are looking for. Once you have used the port scanner, you can use the IP address to connect to the device.

1. What is an IP address?
An IP address is a unique numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. It serves two primary functions – host or network interface identification and location addressing.
2. What is a MAC address?
A MAC (Media Access Control) address is a unique identifier assigned to every network interface controller (NIC) for use as a network address in communications within a network segment.
3. Can I get an IP from a MAC address?
While you cannot directly get an IP address from a MAC address, you can use the MAC address to determine the IP address in some cases.
4. How can I get an IP address from a MAC address?
You can use ARP (Address Resolution Protocol) to map a MAC address to an IP address. You can also use DHCP (Dynamic Host Configuration Protocol) logs to see the list of all assigned IP addresses.
5. What is ARP?
ARP (Address Resolution Protocol) is a communication protocol used for associating an IP address with a MAC address on a local network. It is used for resolving IP addresses to their corresponding MAC addresses.
6. Can ARP be used to get an IP address from a MAC address?
Yes, ARP can be used to map a MAC address to an IP address on the same network segment.
7. What is DHCP?
DHCP (Dynamic Host Configuration Protocol) is a networking protocol that automatically assigns IP addresses and other network configuration settings to devices on a network.
8. Can DHCP logs be used to get an IP address from a MAC address?
Yes, DHCP logs can be used to see the list of all assigned IP addresses and to determine the IP address associated with a particular MAC address.
9. Can I find the IP address of a device in another network segment using the MAC address?
No, you cannot find the IP address of a device in another network segment using the MAC address alone. You would need additional information such as the network topology and routing information to determine the device’s IP address.
10. What is a network topology?
A network topology is the arrangement or pattern of interconnections between nodes on a network. It refers to how devices are connected and how data is transmitted on a network.
11. What is routing?
Routing is the process of selecting the best path for data to travel on a network from one device to another. It involves decisions made by network devices such as routers based on various factors, including network congestion, speed, and distance.
12. What is a router?
A router is a networking device that forwards data packets between computer networks. It acts as an intermediary between devices on different networks and determines the best route for data to take to reach its destination.
13. Can a router be used to determine the IP address of a device from its MAC address?
Yes, a router can be used to determine the IP address of a device from its MAC address, but only if the device is connected to the same network as the router.
In conclusion, getting an IP address from a MAC address can be achieved through various methods. The two main methods include using the command prompt or utilizing a network scanner tool. If a user is comfortable with using the command prompt and can access the DHCP server, the first method is more than enough. If this is not the case, the second method is the most effective way to retrieve the IP address. As stated earlier, it is essential to have the MAC address before attempting any of these methods. By obtaining IP addresses from MAC addresses, users can connect remotely to the relevant devices from anywhere in the world, thus enhancing productivity.
