How does the whole network display IP ownership?

Whole network display IP Place of ownership , How did it happen ？

In order to further standardize the domestic network public opinion , The state stipulates that all Internet platforms need to display IP Attribution information . Microblogging 、 Tiktok 、 Official account and other platforms have been launched in succession IP Home function , This marks the further standardization of domestic speech . But how do Internet platform providers pass IP Locate... In our area ？ What is the principle behind this ？IP What are the practical applications behind the place of belonging ？

How to use IP Address found ？

In our impression , We all know that we can go through IP Address find someone . But when we think about it , We'll find out that IP Address and geographical location are not directly related . Then how did we get through IP The address found the address ？ The answer is ： Through autonomous systems （Autonomous System）.

The Internet is a network composed of different networks , Autonomous system is composed of Internet Large scale network , Connect to Internet Every computer or device in is connected to a AS. And every autonomous system has a code , We call it ASN.

It can be said that AS Similar to a post office in a town . Mail goes from one post office to another , Until you reach the right town , Then the post office in the town will deliver mail in the town . Every AS All control a specific set of IP Address , Just as the post office in each town is responsible for delivering mail to all addresses in the town . Usually , Every AS By a single large organization （ for example Internet Service provider （ISP）、 Large enterprise technology companies 、 Universities or government agencies ） operating .

Come here , We can clarify such a logical relationship ：IP Address -> Address block -> Autonomous network coding （ASN） -> organization -> Country . adopt IP Address , We can locate a general geographical location , for example ： Chaoyang District of Beijing 、 Nanshan District, Shenzhen, etc . For example, my present IP The address belongs to the code AS4xxx This autonomous network , Through this ASN You can know the location is in Shenzhen, China , This ASN The organization of the code is China Telecom .

But by ASN You can only find the geographical location at the county or district level , No matter how thin the position is, you can't find it . But sometimes students say ： He was checked on the water meter , Directly locate a unit or a household ？ In fact, the principle is very simple ！ As we said above, it can be based on IP Address to ASN Organization , and ASN The organization is IP When assigning addresses , Will be carried out IP Address assignment record .

Some IP Who is the address assigned to , All recorded clearly . So the police uncle wants you to have tea , It's not just a matter of grasping one by one . But a hint is , Not everyone has the right to query these data from operators . So those who say they can climb the Internet cable to find you , Basically, you can ignore , It's all scaring you . Only the police uncle filed a case , And the data can be queried only after the relevant procedures are presented .

IP The privacy of the address

Is it that only operators can find someone's address information ？ In the age of big data , Various Internet applications collect a lot of data and information , They can actually use this information , Infer someone's approximate address location . For example, baidu map will always use App SDK And the way the web page records IP Association with address location , And allow reverse queries , That is, according to IP Address reverse query to a certain location , This data may be accurate to hundreds of meters .

In fact, not only domestic companies will do this , In fact, foreign companies will do the same , Like Google And I did . But foreign countries have very strict control on this aspect , Therefore, they will clearly disclose the user's privacy data used , It also provides corresponding functions to enable users to turn off .

A friend said , Then I can use VPN change IP, Is that something App I don't know my exact location ？ It's not , Because your neighbor can betray you . some App Find out , Around the neighbors WIFI、 Bluetooth is very similar to yours . And when someone WiFi When the signal disappears , The neighbors also disappeared simultaneously . Then they can guess , You hide your truth IP, Your geographical location is very close to your neighbors . This is the application in the era of big data .

therefore , When some devices pop up 「 Whether to allow scanning of local devices 」 when , You have to choose carefully . If it wasn't for the intranet NAS Or screen projection , There is basically no need to allow this operation , This operation is stealing your personal privacy information . If you allow this operation , Then he will start scanning the device information of the whole lan , Then write it down . Final , It will your IP Address 、 mobile phone IMEI、WiFi When the information is put together , So as to make some commercial information , for example —— You searched the keyword house on the computer , After you brush your mobile phone, Tiktok will push you real estate advertisements .

To put it bluntly ,「 Find and connect to devices on your local network 」 The use of provides convenience for cross platform advertising , From the perspective of personal information protection and privacy protection experience , This kind of monitoring of equipment 、 Tracking may cause concern to users .
