What is Networking? — THM Walkthrough
Hello everyone, I am Samarth Dad aka h4xpl0it. Today, I am gonna explain to you all about Networking and we will see some practical examples also. With this, let’s dive into it.
You can find this room on TryHackMe, in the path, Pre-Security.
The above screenshot explains about What is Networking. Now, let’s understand the diagram.
Alice, Bob, and Jim formed a network to communicate between them and this is only possible using networking. We will see this in-depth knowledge.
Let’s understand, What is Internet?
In the above screenshot, let’s see that Alice, Bob, and Jim are already connected to each other and they are communicating. Now, Alice wants to introduce Zayn and Toby in front of Bob and Jim. Now, in this condition, Alice starts introducing them to each other to make a successful connection between each user.
In terms of the Internet, it is a very large collection of small devices. As you can see in the above screenshot, you will able to see that there are various networks and they all are connected to one router (Internet).
Identifying Devices on a Network
Identifying devices on a Network is similar to finding an address of a home in any society. In both works, you need something relevant to a path so that you will reach there.
As here, for identification of a device on the Network requires a unique address known as an IP address.
We are getting some IP address of networks.
These two devices will be able to use their private IP addresses to communicate with each other. However, any data sent to the Internet from either of these devices will be identified by the same public IP address. Public IP addresses are given by your Internet Service Provider (or ISP) at a monthly fee (your bill!)
MAC Address
Devices on a network will all have a physical network interface, which is a microchip board found on the device’s motherboard. This network interface is assigned a unique address at the factory it was built at, called a MAC (Media Access Control ) address. The MAC address is a sixteen-character hexadecimal number (a base sixteen numbering system used in computing to represent numbers) split into two’s and separated by a colon, for example, a4:c3:f0:85:ac:2d. The first six characters represent the company that made the network interface, and the last six is a unique number.
We have to open the site and you can see the flag in the popup.
Ping(ICMP)
Ping is one of the most fundamental network tools available to us. Ping uses ICMP (Internet Control Message Protocol) packets to determine the performance of a connection between devices, for example, if the connection exists or is reliable.
Now, in the ping request, you can see the flag. We will now see the next task.
We will see Intro to LAN in the next blog.
Thank you! I hope you will learn something new from this blog. Stay tuned for upcoming blogs……
