How can I simulate IP capture to collect Baidu search result data based on regional IP addresses? The data obtained by Baidu is determined based on the IP address of the region, and the results are different. for example, when users in Beijing and Guangdong search for hospital keywords, the displayed division results are different. Now I want to capture Baidu's r

Paragraph code is my search on the Internet related solutions found, this class Makepregip function logic is a bit of a problem, I modified the next can be used. This class has the function is to allow the white list of IP address access, if you want to achieve restricted blacklist IP address access, simply modify the Checkip function in the code logic can be. How to use The code is as follows

Collection and prevention of collection is a prolonged topic, on the one hand want to engage in other people's things, on the other hand do not want their own things to get away. This article describes how to use Nginx shielding IP to achieve the prevention of collection, of course, can also be achieved through iptable. 1.

In my personal experience of using, I have different working environment, such as the company and home, the company requires fixed IP, and the home is the use of automatic access to IP, so I found this code on the Internet, and after their own changes, you can directly double-click the operation can be convenient to switch IP address. Here the main use of Netsh

operating system and protocol software to manage the main tasks related to the network access layer. The modularization of the protocol stack enables software components in the network access layer dealing with hardware to provide interfaces for the upper layers unrelated to hardware. Network access layer and OSI model-- The physical layer in the OSI model is responsible for converting data frames into bit streams suitable for transmission media. The data link layer completes two independent ta

The IP protocol is the most important protocol in the family of TCP/IP protocols, which provides unreliable, non-connected datagram transport services. So understanding IP protocols is critical to our learning network.IP headerImportant Field Introduction：4bit First ministerial degree: in 4 bytes, determines the IP hea

International regulations: divide all IP addresses into A, B, C, D, and E. Class DefaultSubnet Mask: Class A is 255.0.0.0; Class B is 255.255.0.0; Class C is 255.255.255.255.0. The subnet mask is a 32-bit address. It is used to shield a part of the IP address to distinguish the network ID and host ID, and shows whether the IP address is on the LAN or on a remote
