Subnet mask (Subnet masks): The subnet mask is used to identify which part of the IP address is a network address. Which part is the host address, there are 1 and 0 components, long 32 bits, all 1 of bits represent the network number. Not all networks require subnets, so there are 1 concepts: The default subnet mask (

IP addresses, subnet masks, and gateways in network management are the basic knowledge that each network administrator must master. Only by mastering them can you really understand the TCP/IP protocol settings. The following describes what a subnet mask is.To understand what the subnet mask is, you must understand the composition of the IP address. The Internet i

First of all, our premise is the local area network, so we mentioned the modification more specifically, is to find the subnet mask and the default gateway for proper padding. Here are two specific ways to do this: Method One, we find any other networked computer on the same LAN, locate and double-click the local connected Internet Protocol (TCP/IP) entry, and populate the subnet mask and default g

What are IP addresses, subnet masks, routes, and gateways? Often friends ask me, indeed these terms are often seen by us, today to the people to talk about the meaning of these terms:1.IP Address:The IP address has a 32-bit connection address, consisting of 4 8-bit fields, a 8-bit field called a 8-bit group, and each 8-bit group is separated by a dot to identifyTCP/IP host. Each IP address contains two parts: the network ID and the host ID, the networ

protocol, all the "0" Network numbers are interpreted as "local" networks.* Return addressClass A network address 127 is a reserved address for network software testing and communication between local processes. It is called loopback address ). No matter what program, once data is sent using the return address, the protocol software returns immediately without any network transmission.According to TCP/IP protocol, 1. Groups with network numbers 127 cannot appear on any network. 2. The host and

/** * 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 IP address and subnet mask

method One: First locate any other networked computer on the same LAN, and then double-click the Local Internet Protocol (TCP/IP) entry, and fill in the default gateway and subnet mask inside the computer. 　　Method Two: 1, find the same LAN other normal operation of the computer, click on the Win+r key combination, in the pop-up dialog box directly input cmd, and then click Enter; 2, came to the Msdos interface, will pop up a cut interface,

In TCP/IP, subnet masks are used to determine whether hosts on the network are in the same network segment. In A large network, the subnet masks of class a are 255.0.0.0, The subnet masks of class B is 255.255.0.0, And the SUBNET MASKS of CLASS C is 255.255.255.0. Assume that the s
