On the computer screen in front of Dong Dapeng, Brother Xu's avatar finally lit up, and he asked Dong Dapeng nonchalantly: (Have you thought clearly?

This sentence is exactly the same as the one he asked Luo Qingyang at the beginning, don't look at this sentence as simple, in fact, there are many mysteries in this question, as long as the other party answers, you can learn a lot of useful information.

Asking "you" if you have thought it through is equivalent to transferring all the risks to "you". It is the "me" that "you" came to after thinking clearly, and "you" came voluntarily, not "me" to induce "you" to come. Even if he goes to court, he can use this sentence to exonerate himself.

Ask your family if they know it, and you need to find out what your family is like. But if you have a family and a room, how can the relatives of the family agree to let you sell the organs in your body?

And among those who are homeless, you have to deduce from your further speech whether you are really desperate and need to sell your kidney, or if you are just hot-headed and crazy.

Dong Dapeng immediately replied to him according to the plot that had already been arranged: (I really have no choice, Brother Xu, I owe someone a lot of gambling debts, and if I don't pay back the money, the creditor will cut off my hand!Can you help me? I'm really anxious to use the money!)

Shi Jinshan came behind Dong Dapeng at this time, and when he saw that Brother Xu was really online, he asked excitedly: "Xiao Dong, quickly check his IP address!"

Every computer and other Internet device on the Internet, such as tablets, mobile phones, etc., will be assigned a globally unique IP address by the broadband operator, which is equivalent to the ID card of the Internet device.

It is precisely because of this unique IP address in the world that users can efficiently and conveniently select the object they are looking for from thousands of computers when connecting to computers all over the world through the Internet.

But you can find people by IP address, and others can also find you by IP address!

"Captain Shi, it's already being checked, and it will take some time. Dong Dapeng opened a can of cold drink in his hand and took a sip proudly. A large part of his weight surge in recent years is related to this sugary drink, but unfortunately there is no way, just can't quit.

At this time, Dong Dapeng's computer desktop had opened another software, and a long list of numbers was running non-stop.

As soon as Brother Xu's QQ message came, it was equivalent to establishing a connection between his and Dong Dapeng's two computers. Dong Dapeng is now deciphering the other party's IP address through special software.

As long as you have this IP address, and then access the background database of the corresponding broadband operator, you can immediately know the specific geographical location of this IP.

Some people may wonder how broadband operators can know the specific geographical location of IP addresses when they are all virtual.

In fact, if you think about this carefully, you will understand that there are only three broadband operators in China, and now all of them require customers to register with their real names when handling business.

Your home address, contact number, and even ID photo are all backed up in your broadband operator's backend database.

As long as you have an IP address, enter the background database to check which broadband user this IP is assigned to, and the address will immediately come out.

The number that has been running on the computer screen has finally stopped, 202.102.66.119, Brother Xu's IP address is this!

Dong Dapeng excitedly opened another software and connected to the background of the broadband operator, but before the string of IP numbers could be entered, I saw that the string of numbers began to run again!

"What's going on?" Old Yu Tou was really a layman in terms of network technology, but when he saw that the string of numbers that had just stopped just now was rolling again, he still had a premonition that something was not quite right.

"This ...... This one...... I don't know very well......" Dong Dapeng scratched his head, and then looked at Brother Xu's avatar on the screen, it turned into a gray state of not being online, could it be that the other party actually saw that there was something wrong with him?

Time passed minute by minute, and beads of sweat oozed from Dong Dapeng's forehead. The brothers of the entire task force are all around this office staring at him, and if he loses face, he will be thrown to his grandmother's house.

…………

On the other side of the city, Brother Xu, who had just finished drinking morning tea at this time, was wandering out of the teahouse.

As a southerner, Brother Xu has the habit of going out to drink morning tea every morning. Call a pot of strong tea, and then have a few snacks, chew and taste it slowly, how beautiful.

He looked up at the sky, the sky was cloudy today, and the air seemed unusually hot, and it was time for a heavy rain to pour down to wash away the dullness.

Brother Xu touched his mobile phone and looked at it, after leaving the teahouse, there was no WIFI, and QQ really had no news for a long time. He quickly fiddled with it a few times, logged in again with the traffic, and hurriedly saw that the gambler just now was still there.

Yesterday, Luo Qingyang suddenly disappeared, which made Brother Xu very annoyed. Today, another one took the initiative to send it to the door, which can't be easily missed.

…………

Seeing that Brother Xu's avatar lit up again, Dong Dapeng almost jumped up from the chair in excitement.

He continued to chat with Brother Xu about messy things, and when the IP address was locked, he immediately entered it into the background database and checked it clearly!

"Yo, it's better to use the network on the mobile phone with 4G data, which is more convenient to check the location!" Dong Dapeng opened a software that looked like a map, and after a while, three red dots marked a shining triangle area on the map.

"What kind of high-tech is this?" Old Yu sat on the side and watched in the clouds, now these latest technical investigation methods are too high-tech, and they are far from something that their old guys can play with.

"Yu team, this is a base station positioning system, which can locate the specific location of the mobile phone. Dong Dapeng saw that they were all confused, so he hurriedly popularized science.

After our mobile phone is turned on by inserting a SIM card, it needs to search for the surrounding base station information, that is, to find a signal. Usually in places with a signal in the city, the number of base stations that can be searched by the mobile phone must be more than one, just as your mobile phone can definitely search for the signal of more than one wireless router in the community.

The phone then automatically selects the closest connection with the best signal from these base stations to register.

But the rest of the base stations don't need to be used? No, the phone is still searching for them.

Once you leave base station A for a certain distance, and the signal of base station A is not as good as that of base station B, the mobile phone will automatically switch to base station B.

When the network coverage of the base station is dense to a certain extent, the base station positioning also comes into being.

As long as the mobile phone searches for the signal of at least three base stations at the same time, because the location of the base station is fixed, the specific location of the mobile phone can be tracked immediately according to the distance of the signal between the three base stations, and the error will not exceed three meters!

"According to the analysis given by this positioning system, this Brother Xu should be active in this part of the Yuheyuan community now! As long as he stops, he can immediately locate the specific location!" Dong Dapeng pointed to the triangular area on the map with a determined expression.

Shi Jinshan pinched the butt of his cigarette and decisively gave the order to attack!"Then what are you waiting for, let's go!Xiao Dong, you stay here and continue to stabilize this Brother Xu, if there is any further precise location, call us immediately." ”
