HJ18 identifies valid IP addresses and masks and performs classification statistics, and HJ39 judges whether two IPs belong to the same subnet [string, simulation]
Description Please analyze the IP address and the corresponding mask for classification and identification. It is required to classify according to A/B/C/D/E addresses, and illegal addresses and masks are classified separately. All IP addresses are divided into five categories: A, B, C, D, and E Class A addresses from 1.0.0.0 to 126.255.255.255; Class B addresses […]
Divide the subnet, and then use eNSP to configure static routing for the router, so that PCs can communicate
1. Experiment content 1. Divide the network segment 192.168.1.0/25 into four subnets as needed 2. Configure a static ip for the router so that PC1 and PC2 can ping through. 2. Experimental topology 3. Experimental process (1) Subnetting For a given subnet 192.168.1.0/25, it needs to be divided into 4 network segments according to topology […]
The linux c ioctl interface realizes the acquisition and setting of local IP and subnet mask
In daily development, the need to set up the local network cannot be avoided. Generally, we use the system interface for temporary IP modification, or open, rend write, and operate network files such as /etc/network/interface to achieve permanent IP modification, but Such a modification method is relatively low-end. In fact, there is a universal interface […]
IP address, subnet mask, gateway (Linux view and configuration)
1.IP address IP address = network address + host address, hosts with the same network address (network number) are hosts in the local network and can communicate with each other directly, while hosts with different network addresses are hosts in the remote network, and the mutual communication must be through the local Gateway (Gateway). Including […]
