the global uniqueness of the network address. The host address is allocated by the administrator of each network. Therefore, the uniqueness of the network address and the host address in the network ensure the global uniqueness of the IP address.
Ii. Dividing subnets
To improve the efficiency of IP address usage, you can divide a network into subnets: by taking the bits, you can change from the maximum bi

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
/** * 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
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

What is an IP addressThe so-called IP address is a 32bit address assigned to each host connected to the Internet. In accordance with the TCP/IP protocol, IPs are represented by binary, each IP address is 32bit long and bits are converted to bytes, which is 4 bytes. For example, a binary form of the
the need to request a purchase.Subnet Mask:The subnet mask is not an address, it is used to determine which part of an IP address is the network ID, which part is the host ID, the portion of a continuous 1 represents the network ID, and a continuous portion of 0 represents the host ID. For example, the first 24 bits of Class C network are the network number and the last 8 bits are the host number. Then the
1000 computers can allocate IP addresses and subnet masks in a Class B network, which can have 65 534 hosts. When the number of enterprise users is, you must use a Class B IP address segment. Obviously, in many cases, many IP address segments are useless (for example, there are only about 300 nodes in the Network), whi

Demand Evolution-> you need to find the IP address range: steps for network mask, subnet address, broadcast address, minimum address, and maximum address: 1. take 113.73.0.0/17 as an example. The detailed calculation is as follows: 2.

Subnet Mask and IP address operation subnet mask: function: divide an IP address into two parts: network address and host address. Once the subnet mask is set, the network address and host address are fixed. Calculation: Convert the IP
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 of the two computers perform the and operation, if the result is the same, the two computers are on the same sub-network and can comm
