ip address subnet mask default gateway calculator

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

a period of time.　　Experiment Design　　We designed a simple experiment to help students understand the basic concepts and principles involved in the three knowledge points. In the experiment, we use the ping command to check whether two-way communication can be performed between hosts. During the ping process, the source host sends an ICMP echo request packet to the target host. After receiving the packet, the target host sends an ICMP Echo Reply packet to the source host, in this way, the sourc

subnets will need to occupy 1 bits of the original host identity bit. At this point the network number bit becomes 22 bits and the host label becomes 7 bits. Similarly borrowing 2 host bits can divide a class C network into 4 subnets ... How did the computer know if the network was divided into subnets? This can be seen from the subnet mask. The subnet
