Before launching various "hacker behaviors", hackers will take various measures to detect (or "detect") The host information of the other party, in order to determine the most effective method to achieve your goal. Let's see how hackers know the most basic network information-the IP address of the other party, and how users can prevent their own IP

1. External network IPIP addresses can be easily divided into two categories. An extranet or public IP is a device that uniquely identifies you on the Internet.

In the formal conduct of various "hacker behavior", the hacker will take various means to detect (also can say "reconnaissance") the other party's host information, in order to determine the most effective way to achieve their goals. Take a look at how hackers learn the most basic network information-the IP address of each other, and how users can protect themselves from

file, do I write 6C in front or 49 in front? If you write 6C in front, it is big endian. Write 49 in front, that is, little endian. The word "endian" comes from Gulliver travel notes. The civil war in the minor people's country originated from the fact that the Big-Endian attack or the Little-Endian attack were initiated when the eggs were eaten. as a result, there were six rebels, one of the emperors gave life and the other lost the throne. We generally translate endian into byte order, and ca
