machine, right-click the network in the lower right corner, open the Network Center, you will see this:Settings, Properties-"ip4-" settingHere the IP address is preferably the virtual machine inside the gateway set;After setting up, let's try it and see if we can ping it through:Can ping the pass, then we set his hostname:Here, basically the virtual machine system can be used, we can use Remote Tools to co

IP address segment: 210.143.144.1 ~ 210.143.159.254, 210.143. (1001) 0000.00000000 indicates the network address and identifies a network, 210.143. (1001) 1111.11111111 is the broadcast address, which can broadcast messages to all addresses in the network. This CIDR block is equivalent to 210.143.144.0/20, that is, 210

This article mainly introduces how to use Python to calculate network segments based on IP addresses and subnet masks. It involves Python character string operation techniques based on the Linux platform and has some reference value, for more information about how to use Python to calculate network segments based on IP addresses and

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
