Why can t some IPs find the location?。。 Said the format is incorrect

Dynamic IP addresses are random IP addresses that are assigned when needed. Dynamic IP address and static IP address are corresponding, the so-called dynamic means that every time you go online, Telecom will randomly assign an IP address, static refers to the fixed allocation of an IP address, every time you use this address. Because IP address resources are very valuable, the IP addresses used by most users when surfing the Internet are dynamic, just like computers that access the Internet through modem, isdn, adsl, wired broadband, cell broadband, etc., are temporarily randomly assigned an IP address every time they go online.

An IP address is a 32-bit binary number of addresses, and theoretically, there are about 4 billion (2 to the 32nd power) possible address combinations, which seems like a large address space. Actually, according to....

This is for the security of computer users, not all users can see each other's IP very casually, generally only see the first two fields of IP, such as: this is normal, if your IP is always exposed outside, I am afraid that it will often attract virus attacks from outsiders, for individuals do not matter, if the bank or corporate secrets are introduced to the Internet and expose the IP, the resulting losses are difficult to estimate!

It may be due to changes in the following areas:

1. Due to the operator's IP assignment or IP change, you often log in on different IPs.

2. You are a dial-up Internet user or mobile Internet user, and the IP assigned by the network provider changes frequently.

3. The last time you logged in to QQ, you used ** server.

Cause: Carrier IP Assignment Problem (or IP Change): If the carrier's IP assignment is wrong (or IP changes), the real IP address will be different from the IP address matched by Tencent's IP database. At this point, you can find it in the

Your Current IP" page, we will add updates in a timely manner, and display the update results on the "Your Shared IPs" page. We will constantly update the IP database information and strive to eliminate such causes.

At the same time, please understand that the IP database is not 100% accurate.

Reason 3: If you use the Internet, the geographical location of the server you use is displayed on QQ, which may be different from your current actual location.
