appended with the frame head and frame end of the data link, and the packet is put into frame. Finally, the physical layer is converted to bits-per-unit data. Therefore, the IP address is the network layer used to identify the logical address of different locations, its length is 32 bits, and at the data link layer is the MAC (media access control)

I was so happy to receive two CDs of Ubuntu7.10, each of which is 32-bit and 64-bit, sent by the Netherlands free mail. It took more than an hour to successfully install it on the old machine. Because the school IP address is bound to the MAC address, the old machine cannot obtain the IP

Every week changes between the lab and the dormitory. The lab's damn public router locks the IP address. The Dynamic IP address is always an incorrect address, and can only be manually modified once. Then I was so lazy and didn't want to open the graphical interface to perfo

Today, we have encountered the problem of implementing multi-network segments in Linux. In the past, we only had to pay attention to how to modify the Linux route. When using the 2003 system, we often access multiple network segments with a single Nic. The premise is to bind an IP address for each CIDR block first. Similarly, if we need to enable the Linux Nic to access multiple network segments, we must fi

users to directly view the Intranet host. For this reason, the external services on some hosts cannot be directly accessed by Internet users. Therefore, the concept of port ing is introduced. In this case, you must map the external service port of the Intranet host to the public IP address through port ing, so that the Internet user can access your public IP

This is the reason to call the Sina API interface, mainly to avoid our local storage of an IP attribution repository,At the same time, we have to store the user's IP locally, only the IP can be stored, no need to store its location, save a field.For example, write a Web page with the IP

, switch the main interface to a DOS environment, enter the "Netsh" command at the command line, click the Enter key, the DOS command prompt will automatically become "netsh>", followed by "Interface" | IP command, the DOS command prompt becomes "Interface ip>" (as shown in Figure 1), where you enter the IP setup mode. In this mode, you can use the "set" command
