masks, and address classifications can be divided and addressed together. The absence of any of the three elements will lead to logical vulnerabilities. The last problem: Similarly, in a LAN, theoretically we also need to split subnets of varying sizes, which also need to classify IP addresses, for example, 10.0.0.0/8 is divided into 10.0.0.0/16 ~ 10.127.0.0/16 and 10.128.0.0/24 ~ 10.191.255.0/24, etc. Ask the network administrator about the feasibility and operation. Finally, attach a very use

three bytes. FAQ: What? You still don't understand? Ask me why do I do ' and ' arithmetic instead of anything else?　　In fact, you should be able to understand the above example carefully. ' 1 ' in doing ' and ' operations, does not affect the result, ' 0 ' in doing ' and ' operations, will get 0, the use of ' and ' this feature, when the administrator set the subnet mask, the

number bits are set to 1, and the host number is set to 0. Default subnet mask of A-class network: 255.0.0.0 B-class network default subnet mask: 255.255.0.0 C-class network default subnet mask: 255.255.255.0 2)

Windows to bring a calculator on the line.) Open Calculator, point to view > scientific type, enter decimal number, then click "Binary" This single point, you can switch to binary. ）Switch the netmask to binary, and we'll find that all the subnet masks are made up of a string of [red] continuous [/red] 1 and a string of [red] continuous [/red] 0 (altogether 4 se

. (Some people say that I won't change it. It doesn't matter. We can use the built-in calculator in windows. Open the calculator, click View> scientific type, enter a decimal number, and click the "binary" Single-Choice Point to switch to binary .)After switching the subnet mask to binary, we will find that all the

Network Segment Encyclopedia business cards A cidr Block refers to the part in a computer network that uses the same physical layer device (transport medium, repeater, hub, and so on) for direct communication. From one IP address to another, it is like a network segment from 192.168.0.1 to 192.168.255.255. Network Segment The subnet mask assigned by the IP address is only 255 or 0 in each segment by defa

IP Address Subnet mask calculation, return IP segment start and end range, length, mask and other information. /** * Mask Calculator * @author Weaksun * @param string $ip IP * @param Numeric $bits
