In order to further regulate domestic online public opinion, the state has stipulated that all Internet platforms need to display IP place-of-place information. Several platforms, such as microblogging, tremors, and public numbers, have gone online. IP place functions, signaling a further normativeization of domestic discourse. But how do Internet platform providers locate our area through IP? What are the underlying principles? What are the practical applications behind IP place of belonging?

In order to further regulate domestic online public opinion, the state requires that all Internet platforms display IP attribution information. Several platforms, such as microblogging, shivering, and public numbers, are online IP attribution functions, signaling a further normativeization of domestic discourse.

In our impression, we all know that someone can be found through an IP address. But when we think about it, we find out that the IP address is not directly related to geographic location. So how do we find the address through an IP address?

The Internet is a network of different networks, and the autonomous system is a large network that makes up the Internet, and every computer or device connected to the Internet is connected to an AS. Each autonomous system has a code that we call the ASN.

AS is considered to be similar to a town's post office. Mail goes from one post office to another until it reaches the right town, where the city's post office transmits mail. Each AS controls a specific set of IP addresses, just like every town's post office is responsible for transmitting mail to all addresses in the town. Usually, each AS is operated by a single large organization (e.g. Internet service providers (ISPs), large enterprise technology companies, universities or government agencies).

到这里，我们可以捋清楚这样一个逻辑关系：<code>IP地址 -&gt; 地址块 -&gt; 自治网络编码（ASN） -&gt; 组织 -&gt; 国家</code>。通过 IP 地址，我们就可以定位到一个大致的地理位置，例如：北京朝阳区、深圳南山区等。例如我现在的 IP 地址就归属于编码为 <code>AS4xxx</code> 这个自治网络，通过这个 ASN 可以知道位置在中国深圳，这个 ASN 编码所属的组织为 <code>中国电信</code>。

But the ASN can only be located in a district or district location. But how come people sometimes say, "He's been searched for a water watch and located directly in a particular unit?" The principle is simple! It says that the IP address can be located in an organization of ASN, and the ASN organization will be doing IP address distribution records when it does IP address allocation. Only an IP address is assigned to anyone, and it is clearly recorded. So uncle of the police wants to ask you for tea, and that's not a good idea. The point is to point out that not everyone has the authority to access the data. So those who say they can climb the web to find you can basically ignore it.

Is it possible only the operator can find a person’s address information? Today in the big data age, a large amount of data is collected by various Internet applications, and they can actually extrapolate a person’s general address location from that information. For example, 100-degree maps will always record IP and address location connections in the way App SDK and the web page, and allow reverse queries, that is to say, to search a location backwards from an IP address, and this data is likely to be accurate to hundreds of metres.

In fact, it is not only domestic firms that do this, but foreign companies do the same, for example Google. Only very strict controls are exercised abroad, so that they can more clearly disclose the user’s privacy data used and also provide a matching function that allows users to shut down.

Some friends say I can change IPs with VPNs, and some Apps don't know exactly where I am. No, because your neighbors can sell you out. Some Apps find that the neighbors' WIFIs, blue teeth, etc. look very much like you. And when some WiFi signals disappear, the neighbors disappear in sync. Then they can guess that you've hidden your real IPs, your geographical location and your neighbors' proximity. That's what you're doing in the context of the big data age.

So, when some equipment pops up with a hint whether it's allowed to scan the local device, you have to choose carefully. If it's not an in-line NAS or a screen drop, there's no need to allow this operation, which is stealing your personal privacy information. If you allow it, he starts scanning the entire LAN equipment information, and then records it. Eventually, it aggregates your IP address, your cell phone IMEI, WiFi, etc., and makes some commercial information, for example -- you search the key word house on the computer, and then you swipe your real estate ad.

To be clear, the use of "Finding and Connecting Devices on Local Networks" facilitates cross-platform advertising, and such monitoring and tracking of equipment may cause concern to users in terms of personal information protection and privacy protection experiences.

The whole net shows IP belonging, the technology behind it, you know?
