There are 3 classes A, B and C. If in Class A, we will be able to have 16 million addresses, in Class B there are 65536 addresses. For example : In class B with 132.25 , we have all addresses from 132.25.0.0 to 132.25.255.255 . The majority of A class addresses are owned by companies or organizations.

An ISP usually has several class B or C addresses. For example: If your IP address is 132.25.23.24 , you can determine who your ISP is.

However, it is possible to change your IP, which means you can send a fake information to another computer that will believe that the information received comes from a certain machine (of course not yours). ). You can pass the server without having to control the server. The drawback is that the feedback from the server will be sent to the IP-enabled device that we forged. So you probably won't get the feedback you want. Perhaps the only thing that spoof IPs is effective is when you need to pass a firewall, steal your account and need to hide your personal information.

3. Worm : This is a standalone program that can replicate itself and spread throughout the network. Just like a virus, it can also damage data or it can destroy inside the network, even cracking that network.
4. Logicbomb : A program that sends a lot of data packets to the same address at the same time, flooding the system, blocking traffic lines (on the server) or using it as a tool to ' terrorize ' the enemy.
