Computer error: [IP address conflicts with other URLs] How to solve it?

Question 1: The local connection IP is 196.******.1 which is the intranet address. Set the intranet IP of machine B to 196.******.2. Just use the default netmask. Question 2: It may be caused by the stricter version of the genuine version and the comprehensive system process. This is also the reason why the genuine version is safer! ! ! Question 3: IP conflict: 1. Many users do not know much about TCP/IP and do not know how to set parameters such as "IP address", "Subnet mask", and "Default gateway". Sometimes users do not get them from the administrator. information of the above parameters, or the user has unintentionally modified this information; 2. When the administrator or user sets the above parameters provided by the administrator, the parameters are entered incorrectly due to errors; 3. During client maintenance and debugging, the maintenance personnel use Caused by the use of temporary IP addresses; 4. Someone steals other people's IP addresses. Question 4: It may be that the last time you used QQ and other software that can display IP was in an Internet cafe. It will be fine if you log off and log on again. I often encounter this situation and made a lot of jokes. It's okay if someone steals your IP. You should not be able to let the IP go to the Internet. The same IP is not allowed in the network. Solution After receiving the conflict report, we first determine the VLAN where the conflict occurs. Find the network segment where the conflicting address is located through the VLAN definition of the IP plan and the conflicting IP address. This is critical to successfully finding the network card MAC address, because some network commands cannot be accessed across network segments. First, isolate the client computer from the network and allow the computer with an illegal IP address to run on the Internet, so that the network administrator can try to find it. Application network test commands include ping command and arp command. Use the ping command, assuming that the conflicting IP address is 10.119.40.40. In the msdos window, the command format is as follows, where the italicized part is the command result. C:\WIDOWS\〉ping 10.119.40.40 Request timed out Reply from 10.119.40.40: bytes=32 time〈1ms TTL=128 The reason why we want to ping this machine is for two purposes. First, we need to know that we The machine we are looking for is indeed on the network. Secondly, we need to know the MAC address of the network card of this machine. So how do we know its MAC address? This requires the use of the second command arp: the arp command can only be used in a certain VLAN. It is a low-layer protocol and cannot cross routes. C:\WIDOWS\〉arp -a Interface: ...... on Inerface ... Internet Address/Physical Address/Type 10.119.40.40/00-00-21-34-63-56/ dynamic The following is a slightly above list It shows that the MAC address of the network card at the conflicting IP address 10.119.40.40 is 00-00-21-34-63-56. The next thing we are looking for is the specific physical location of the network card with the MAC address 00-00-21-34-63-56. It has been explained in the network introduction that the network card of each client is directly connected to the second-level switch. Next, facing a large number of Ethernet switches, we need to find the switch port corresponding to the conflicting MAC. The device connected to the customer in this network is Bay's 303/304. This article uses 303 as an example to describe how to find the port location of a certain MAC address. There are many methods for Bay303's network management. The following only describes the method of finding illegal MAC using the Web browser method. Before searching, you must first determine the location of the switches in the VLAN and find out the IP addresses of these switches. You can use the switch addresses to access the network management information of the switch.

* Start the browser on the network administrator's machine * Type in the IP address of the switch * Enter the user name and password after prompting for login information * Enter the "MAC Address Table" option
