Linux generally uses the ifconfig command to modify the IP, gateway, or subnet mask of a Linux host. 1. Command format:ifconfig [Network Devices] [parameters]2. Command function:The Ifconfig command is used to view and configure network devices. This command can be used to configure the network appropriately when the network environment changes. 3. Command parameters:up starts the specified network device/NIC. down to turn off the specified network de

The IP address is composed of four digits. Here, let's take a look at three common IP addresses.Class a ip segments 0.0.0.0 to 127.255.255.255Class B IP segments 128.0.0.0 to 191.255.255.255C-type IP segments 192.0.0.0 to 223.255.255.255The default subnet mask allocated by XP is only 255 or 0 for each segment.Class A default subnet mask 255.0.0.0 a subnet can accommodate up to 16.77 million computersDefault

The Mask filter can make a rectangular mask of HTML component objects on a Web page. What is a mask? If you use the mask in Flash, you will know, that's it. In fact, you can also understand the mask, the equivalent of a colored cloth to cover the object, but the content has

are suitable for small networks such as campus networks, and each class C network can have up to 254 hosts. From the above introduction we know that the IP address is the network number and host number to indicate the host on the network, only in a network number under the computer can be "directly" interoperability, computers with different network numbers need to be connected through gateways. But such a division appears and is very inflexible in some cases. For this reason, the IP network

The freshly-baked javascript image switch effect is achieved by a mosaic mask switch. In Flash, a good implementation of mask animation is very simple, but JS implementation of some difficulties.Xmosaic.js, like Xscroll.js and Xscroll2.js, are JavaScript classes used to make a single image switch effect, but So far the xmosaic.js implementation of the special effects is the most dazzling, dazzle to me after

Canbus ID Filter and MaskCANBUS is a two-wire, Half-duplex, bus based LAN System that's ' collision free '.Data is broadcast onto the bus-there are NO SUCH thng as A Point-to-point CONNECTION as with data LANs.All nodes receive any broadcast data and decide whether or not, data is relevant.A CANBUS B frame consists of a four byte headers (containing a 29-bit identifier), followed by up to 8 data bytes.A receiving node would examine the identifier to decide if it is relevant (e.g. waiting for a

Subnet mask (subnet mask) definitionIt is a bitmask that indicates which bits of an IP address identify the subnet on which the host resides and which bits identify the host. The subnet mask cannot exist alone, it must be used in conjunction with an IP address. The subnet mask has only one function, which is to divide

The Ip2long IP address is converted to an integer type.Long2ip integer data is converted to IP. The subnet mask is converted to a mask length mode:$slash _notation = strlen (Preg_replace ("/0/", "", Decbin (Ip2long ($subnet _mask)));$bits =strpos (Decbin (Ip2long ($mask)), "0"); The subnet mask bit length is converted

The Mask editing box (Maskedit) is a special edit box. Use it to design a number of complex input formats. After selecting Maskedit, you need to design an input format for it. The method is as follows: First select the Maskedit on the form, locate the Editmask property in the Object Viewer (Objects Inspector), double-click it, and pop up a dialog box as shown in the following figure. The Input mask edit b

So, how does this work out? First look at the following two map: You can see that the same image, with the same mask, and then change the position of the mask, you ca

Subnet Mask is the basic knowledge that each network administrator must master. Only by mastering it can you truly understand the TCP/IP protocol settings. The following describes what a subnet mask is. IP address Structure To understand what a subnet mask is, you must understand the composition of IP addresses. The Internet is composed of many small networks, ea

places, while the number of hosts is too small, therefore, the host addresses it provides become increasingly scarce. Currently, in addition to using NAT to allocate reserved addresses within an enterprise, a high-category IP address is usually further divided, to form multiple subnets, which can be used by different user groups. This is mainly to effectively use the IP address in the case of network segmentation. By taking the high part of the host number as the subnet number, we can expand or
