There are not many opportunities to use network knowledge in actual work. Although I have learned it before, it will become unfamiliar without having to use it for a long time. Recently, I got several virtual machines on the cloud and neede
Also Talk About subnet division and subnet Communication 1. network IP address and subnet mask classification: Class A: IP: 0.0.0.0-127.255.255.255.255.255 subnet mask: 255.0.0.0 or labeled as/8 (8 1) Class B: IP: 128.0.0.0-191.255.255.255 subnet mask: 255.255.0.0 or/16 (16
The subnet mask cannot exist alone, it must be used in conjunction with an IP address. The subnet mask has only one function, which is to divide an IP address into two parts: network address and host address.The subnet mask setting must follow certain rules. The same as the IP address, the length of the subnet mask is
As for subnet division, the subnet mask is odd. 1.0.1.0 -- 1.0.3.255 Fujian Telecom converts the subnet mask to an IP segment 1.0.1.0/24--1.0.2.0/23, if two IP addresses are replaced by binary IP addresses in a general way, or the budget is 0001.00000000.00000001.00, the subnet mask may be odd.

Use Python3 to create a TCP port scanner and a python3 Port Scanner
In the initial stage of penetration testing, we usually need to collect information about attack targets, and port scanning is a crucial step in information collection. Through port scanning, we can find out which services are open to the target host, and even predict certain vulnerabilities based on the service. TCP port scanning is genera
