What is the reason why the IP address of the network connection is different from the IP address dis

That could be a problem with the DHCP server, you can ask the network administrator, they must be dying.

Originally, it should be like this, your intranet uses a private IP address, for example,,, and then when you access the outside, it is converted by NAT and replaced with a public IP address, and the general school only has 1 to 4 public IP addresses, for example.

But I guess you won't have a problem, you can first enter "cmd" in "start" and "run", open the dos window, and then enter "ipconfig", you can see your IP address, subnet mask, gateway address, etc., write down your IP address, and then go to the Internet to find a ** (a lot) that can show your IP, display it, and also write it down, and see if the two IP addresses are the same?

The address of "ipconfig" should be the private network address, and the public network address displayed on the web page should be the NAT translation.

Addendum: Our school also uses H3C, you first use the method I said above to see if the two IP addresses are different, right? If the private address is a private address, there must be something wrong with your computer.

If the intranet address does not start with 10,172,192, then you can go to the network administrator, they must have made a mistake, they are going to be scolded by the leader, quack!!

In this way, it seems that your IP address is not assigned by the school's DHCP server, you can call ** to ask the network administrator, and you will say that the IP address from your ipconfig starts with 220, not a private network address, and they will know that it is their problem, and they will definitely come to show you.

Someone may have tampered with your IP address with **.

You can try it like this:

Control Panel - Network & Internet Connection - Internet Options - Connections - LAN Settings - If you use **, then it will be displayed in the **server field, you just need to select 'Auto-detect settings'.

This IP is your total IP, which is an IP that is common to your local area network, that is, your school accesses other places through this IP.

It's the real IP of your machine, you launch it, and then go to the school's ** next thing.

Don't know what you're using to access the Internet within the school?

It's better to be more detailed Maybe the network you use directly belongs to Netcom or Telecom, not to the education network, and your so-called school generally belongs to the IP of the local area network, which does not mean that it is the school intranet.

It's local.,You fill it in yourself.,Generally, the system is filled in.,This doesn't have any effect.,This is the network!

The LAN and extranet need to go through address translation.

You see if you're using **.

In the Internet, in order to distinguish computers all over the world, each computer is assigned a special number, such as an IP address.

To access which **, you need to know the IP address of this **. But the IP address is a boring long string of numbers, and in order to make it easy for people to remember, **again** (or domain name), such as: ".

Every time in a web browser.

Automatically help you "translate" to the corresponding IP address, but one may correspond to several IP addresses, because one** the same content may be stored in many computers, and you will be "transferred" to the IP address closest to your computer.

MAC address, like 24-a3-b3-7c-23-12, as long as the network card parts in the computer are not replaced, this address will never change.

Many ** ending "What do "cn" and "com" mean? What does "www" mean? Just like the address on the envelope when writing a letter, write which country first, then which city, which street, including several levels.

Generally** is divided into 3 or 4 parts, and each part is separated by a small dot. Everyone has to deal with a large number of ** every day, but they may not really "see" **, ** have to look backwards and forwards.

No matter what**, the last part is nothing more than a dozen like "cn" and "com", some of which indicate the type of **, such as "com" is business**, "edu" is education**; Some indicate the country to which ** belongsFor example, "cn" means China and "jp" means Japan. If the last two paragraphs of ** are". As you can guess, this is the business class of China.

Looking further ahead, it is really the name of **.

Summary:The part in front of the first point represents**A host in **, everyone most often sees www, but in fact, it doesn't have to be www, you can also take another name, like www1, bbs, of course, there may be nothing. The letters "www" stand for "worldwideweb" (World Wide Web) is a general term for web services on the Internet.

**Usually refers to the address of a web page on the Internet. Enterprises and institutions or individuals through technical processing, some information is stored on the Internet in a page-by-page manner, and each page has a corresponding address, so that other users can access and obtain information and materials, such an address is called **.

In the Internet, if you want to access another computer from one computer, you have to know the other person's. The ** mentioned here actually refers to two connotations, namely IP address and domain name address. On the surface, these two words are quite professional, but as long as you explain them, you will understand the reason.
