subnet mask for single ip

This example describes a Python implementation method that calculates a network segment based on an IP address and subnet mask. Share to everyone for your reference. Specific as follows: This code is tested in the Linux environment 2.6.6python version! #!/usr/bin/env python#_*_encoding:utf-8_*_#input your IP address

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, 210.143. (1001) 0000.00000000, and 20 indicates the subnet

The following small series for everyone to bring an article WinForm C # get the MAC address, IP address, subnet mask, the default gateway instance. Small series feel very good, now share to everyone, also for everyone to make a reference. Let's take a look at it with a little knitting. 1. Add an assembly 2. Introduce namespaces Using System.Management; 3.

applicable to a small private network and a large world. an IP address is a unique identifier of a single device on an IP network. the IP address consists of 32 binary digits ranging from 0 to 4294967295. this means that theoretically the Internet can contain approximately 4.3 billion unique objects. however, in order
