Five methods to quickly find the peer IP address (1)

When transmitting data with a friend over the network, you sometimes need to know the IP address of the Peer computer before establishing an information transmission channel with the peer.

How can I find the IP address of the other party? You may sneer at this problem. Indeed, querying the IP address of the other computer is not worth mentioning. However, when you want to list multiple IP address search methods, you may feel overwhelmed. Next, this article describes how to quickly and accurately search the computer ip address of a friend of the other party, and proposes the following methods. I believe this will help you!

1. Mail Query Method

When you use this method to query the IP address of the recipient's computer, first ask the recipient to send you an email, and then you can obtain the IP address of the computer where the sender is located by viewing the email attributes; the specific implementation steps of this method are as follows:

First, run the OutLook express program, and click the "accept all emails" button in the toolbar to accept the emails sent by friends. Then, open the inbox page and find the emails sent by friends, right-click and run the "attribute" command from the shortcut menu;

In the Property settings window that opens later, click the Details tab. On the displayed tab page, you will see "published ed: from xiecaiwen (unknown [11.111.45.25]). in this information, "11.111.45.25" is the IP address of the Peer friend. Of course, if the peer friend sends you an email through the WEB mailbox in the Internet, the IP address you see here is not the real IP address of the workstation, but the IP address of the website where the WEB mailbox is located.

Of course, if you are using other mail client programs, the method for viewing the sender's IP address may be different from the above; for example, if you use foxmail to receive emails from friends, then you can select the target email in the inbox, and then click "mail" in the menu bar to select the "original information" command from the drop-down menu, you can see the IP address of the other friend in the interface.

2. log query method

In this way, you can use the firewall to monitor the QQ token record in real time, enable the log record of the firewall, and find the IP address of the Peer friend. This document uses the KV2004 firewall as an example to describe how to search the IP addresses of friends of the other party:

Considering that QQ chat with friends is performed through UDP protocol, you must first set up a KV firewall to automatically monitor the UDP port. Once data is found to have entered from the UDP port, it is automatically recorded. When setting the KV2004 firewall, click "rule Settings" on the firewall interface, and then click "new rule" to bring up the setting window;

Enter "Search IP Address" in the "name" text box in the window, and also enter "Search IP Address" in the "Description" text box. Then, in the "network condition" setting item, select the "Accept data packet" check box and set "IP address of the other party" to "any address", without any configuration in the "local IP Address" settings;

Next, click the "UDP" label, select the "port range" option in the "local port" setting item under the tab page, and enter "0" in the Start box ", enter "65535" in the end box. Similarly, select the "port range" option in the "peer port" setting, and enter "0" in the Start box ", enter 65535 in the end box ".

Next, select the "pass" option in "when all conditions are met" and select the "record" option in "other processing, the "rule object" setting item does not need to be set. After completing all the above settings, click "OK" and return to the main interface of the firewall; select the newly created "Search IP Address" rule in the main interface, and click "save" to save the preceding settings.

After completing the above settings, The KV firewall will automatically monitor the QQ token record throughout the process. Once the other friend sends you QQ information, then, the IP address information of the Peer friend automatically appears in the firewall log.
