Excuse me, colleagues from other places always want my computer IP address. What is this for?

If you are a colleague, the leader asks him to ask for your IP address, for fear that you will not go out to work or go home to work. I don't believe a word you say.

Don't give it to him, lest he do something else in your name. After breaking the law, you will also be jointly and severally liable.

Log in remotely and use your computer.

What is the position of your foreign colleague?

I think you can boldly ask his purpose, even if you don't know what he is describing.

If you are asked the ip address of your local computer, it is usually the ip in the local area network, which usually starts with 192. 168. It doesn't matter if you tell him, unless your company fixes the public IP.

Another situation is that your computer has been mapped by the intranet. Whether it is the mapping of the outbound route or the mapping of the C terminal, you can directly access the information of your computer by obtaining the mapping address of your computer. If your colleague is not engaged in network operation and maintenance, it is very suspicious to ask for this information.

When you use the office computer, there will inevitably be personal information exchange, such as WeChat chat, e-mail, Tik Tok Weibo and other new media interactions. I firmly believe that the news of using the gateway to monitor users' online content has been exposed before, so you'd better have a snack, and your personal information will be exposed if you are not careful.

In short, my colleague asked you about the configuration information of your computer, but I couldn't explain it clearly. Let someone handle it.

First, determine whether your computer is a personal computer or a company office computer. Secondly, does your computer have a server program installed? If it is an office computer with a server installed, your ip is too normal; If not, you can just ask him what he wants.

You can do many things, such as forcing the computer camera to turn on.

The IP address is for direct access to your computer, so don't give it to him.

Your computer can only be accessed by yourself.

First of all, you need to know a little knowledge: the difference between public IP and intranet IP.

Also known as private address or local area network address.

There are three types of private addresses.

Class a:10.0.0-10.255.255.255 mask255.0.0.

Class b:172.16.0.0-172.31.255.255 mask255.255.0.0.

Class c:192.168.0.0-192.168.255.255 mask255.0.

Usually your address is this. This address can only be addressed in the local area network. Generally speaking, these machines that are directly connected through network cables and switches can use this LAN address to address each other. Outside this circle, this address is invalid!

In other words, even if you tell this address to your colleagues in other places, it is useless. Because his machine is not on the same LAN as yours.

This IP address can be addressed from the Internet. Others can connect to network applications (such as remote desktop, ssh server, web service, etc.). ) Run on your computer through this address.

In this case, you should be careful!

If you tell your colleague your address, your colleague can use this address to link to your computer (through the above-mentioned application, there are many others that are not mentioned here).

If it is linked to the remote desktop, he can control your computer, so you need to consider whether you really want to authorize him to control your computer? All your data will be exposed to him!

If your colleague is a network administrator and has the permission of the relevant leader, you should provide your office Internet ip. The function of ip is your address. As long as you know the ip address of your computer, you can get all the data of your computer, including personal privacy.

This is how people used to use other people's computers or other people's computers.

It's convenient to do things remotely.
