Full resolution of both the Intranet and Internet bandwidth users (1)

Many broadband users do not know whether they belong to the Intranet or the Internet, so that they blindly perform port ing and other operations before using software such as BT for download. The following describes in detail the China Telecom ADSL 2 m broadband. For other types of broadband, you can refer to it for judgment. The methods and principles are basically the same.

First, correct a common error. We often hear the saying that "xx adsl is an intranet" or "xx adsl is an Internet" is incorrect. Because "ADSL Broadband" is only a form of service provided by broadband operators, it is only a technology and a service, and there is no concept of Intranet or Internet. The Intranet or Internet we mentioned actually refers to whether the current network location of the end user's computer using this ADSL Broadband Service is Intranet or Internet. In other words, whether an end user's computer is an intranet or an Internet connection is completely related to how he uses the broadband service such as ADSL, but not to what type of broadband he uses.

Next I will give my conclusion and then conduct a detailed analysis:

1. First case: if only one user on a computer is using the broadband, but does not use the routing function, he or she uses dial-up software to directly access the internet, in this case, the current network of the user is the Internet; or, more simply, the computer belongs to the Internet when no changes are made after the Telecommunications Bureau sends someone to install ADSL;

2. Case 2: if a user using China Telecom ADSL sets the routing function in the ADSL modem and multiple users use the same ADSL line to access the Internet, in this case, each computer belongs to the Intranet;

3. Introduce a special form of Broadband: Intranet in the Intranet;

Before specific analysis, first describe the criteria for determining the Intranet and Internet: (reference from the help information of BitComet)

1. judgment criteria: "global statistics" for BitComet of version 0.50 or later, in which the external IP address is the public IP address and the internal IP address is the Intranet IP address, if the two values are the same, you are a public network user; otherwise, you are an intranet user. Of course, Intranet users can achieve the same effect as Internet users through port ing.

2. Criterion 2: Use "Advanced connection information" in MSN Messenger "Tools> Options> connection". Note: MSN Messenger is used, not Windows Messenger. Windows Messenger advanced connection information is different from MSN Messenger ). The advanced connection information consists of the following types:
