Teach you to change the IP address assigned to the network adapter

Network adapter also known as NIC or network interface card (NIC), English name Networkinterfacecard. It is a device that makes computers networked. The usual network adapter is the one that connects the PC to the LAN. The network card (NIC) is plugged into the computer's motherboard slot and is responsible for converting the data that the user wants to pass into a format that can be recognized by other devices on the network and transmitted over a network medium. Its main technical parameters are bandwidth, bus mode, electrical interface mode and so on. Its basic functions are: from parallel to serial data conversion, package assembly and disassembly, network access control, data caching and network signal. Currently, the main 8-bit and 16-bit network card.

The NIC must have two major technologies: the NIC driver and I/O technology. The driver is compatible with the network system and realizes the communication between PC and network. I/O technology can realize the communication between PC and network card through the data bus. Network card is the most basic element of http://www.aliyun.com/zixun/aggregation/11991.html > Computer network. In a computer local area network, if a computer does not have a network card, the computer will not be able to communicate with other computers, that is, this computer and the network are isolated.

Different types of network cards: According to the different networks technology, the network card classification is also different, such as well-known ATM network card, Token Ring and Ethernet network card. According to statistics, at present about 80% of the LAN using Ethernet technology. According to the work of the different objects of the work characteristics of the special design, the price is more expensive, but the performance is very good. In the case of compatible NIC, at present, the network card is generally divided into ordinary workstation network card and server dedicated network card.

Server-specific network card is to adapt to a variety of Web services, performance is also different, can be classified according to the following standards: according to the support bandwidth of the network card can be divided into 10M network card, 100M network card, M Adaptive network card, 1000M network card several; According to the different type of network card bus , EISA network card and PCI network card three categories, which ISA network card and PCI network card more commonly used. The bandwidth of the ISA bus network card is generally the 10M,PCI bus network card bandwidth from 10M to 1000M. The same is the 10M network card, because the ISA bus is 16 bits, and the PCI bus is 32 bits, so the PCI NIC is faster than the ISA NIC.

This article describes how to change the IP address that has been assigned to a network adapter. If your network has a Dynamic Host Configuration Protocol (DHCP) server, the IP address is automatically assigned, otherwise you can specify an IP address.

How to change the IP address assigned to a network adapter

Log on to the computer by using an administrator account.

Click Start, point to Control Panel, point to Network Connection, and then click the local connection you want to modify.

In the Connection Status dialog box, click Properties.

Right-click the local connection you want, and then click Properties. The Local Network Connection Properties dialog box appears.

In this connection use the following items box, click Internet Protocol (TCP/IP), and then click Properties. The Internet Protocol (TCP/IP) Properties dialog box appears.

Continue to perform the steps in one of the following two sections, depending on your environment.

How to obtain an IP address automatically

Follow these steps to configure your computer to obtain an IP address from a DHCP server. Note that you must have a DHCP server.

Click Automatically get IP address.

If you do not want to specify the IP address of the domain Name System (DNS) server, click Automatically obtain DNS server addresses.

Click OK. In the Local Area Connection Properties dialog box, click Close.

In the Local Area Connection Status dialog box, click Close.

Click Start, and then click Run.

In the Open box, type cmd, and then click OK.
At the command prompt, type ipconfig/release, and then press ENTER.
