how to calculate subnet mask from ip address with example

subnet can be "directly" interoperable. So how do you determine the subnet mask? Referring to the IP address sub-network number and host number, to divide a network into multiple subnets, so the network number will occupy the original master, for

QT5 obtains the local IP address, computer name, network connection name, MAC address, subnet mask, and broadcast address.Get Host Name /** Name: get_localmachine_name * function: get the name of the Local Machine * parameter: no * returned: QString */QString CafesClient: ge

PrefaceThis document is simply a logical algorithm, and how to compute network bits, host bits, and broadcast addresses in the case of known IP addresses and subnet masks. All steps are far from the most primitive binary way, the direct hit principle, please read carefully.1. Logic algorithmLogic and operations and logic or operations are used when computing network bits, host addresses, broadcast addresses

IntroductionThis article describes what the IP address and its function and IP address composition, IP address classification, IP subnet par

/** * Get broadcast address * */public static String getbroadcastaddress (string subnet, string IP) {string[] ips = ip.split ("\ \."); string[] subnets = subnet.split ("\ \"); StringBuffer sb = new StringBuffer (), for (int i = 0; i Get the Java implementation of the broadcast address based on the

The subnet mask is used to determine whether the IP addresses of any two computers belong to the same subnetwork. The simplest understanding is that after the IP address and subnet mask
