ip and subnet mask calculator

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

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 Ip2long IP address is converted to an integer type.Long2ip integer data is converted to IP. The subnet mask is converted to a mask length mode:$slash _notation = strlen (Preg_replace ("/0/", "", Decbin (Ip2long ($subnet _mask)

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 operat
