Installation
Install with composer:
composer require "luzrain/ipcalc:~1.0.0"
Basic usage
This class takes both IPv6 and IPv4 addresses into consideration. You can create the class by passing an IP and CIDR mask one of two ways:
require 'vendor/autoload.php';
$net = new IPCalc\IP('fe80:dead:15:a:bad:1dea:11:2234/93');
// or
$net = new IPCalc\IP('fe80:dead:15:a:bad:1dea:11:2234', 93);
You can then access different aspects of a network:
$net->getVersion(); // 6 # IP version
$net->getIp(); // fe80:dead:15:a:bad:1dea:11:2234 # Actual IP address
$net->getCidr() // 93 # Cidr prefix
$net->getNetmask() // ffff:ffff:ffff:ffff:ffff:fff8:: # Netmask in printable format
$net->getNetwork() // fe80:dead:15:a:bad:1de8:: # Address of current IP network (for ipv4)
$net->getBroadcast() // fe80:dead:15:a:bad:1def:ffff:ffff # Broadcast address of network (for ipv4)
$net->getHostMin() // fe80:dead:15:a:bad:1de8:: # First IP adress
$net->getHostMax() // fe80:dead:15:a:bad:1def:ffff:ffff # Last IP adress
There is a __toString()
method which will return a JSON-encoded string on the class object:
echo new IPCalc\IP('192.168.1.10/24');
The above would return:
{
"version":4,
"ip":"192.168.1.10",
"cidr":24,
"netmask":"255.255.255.0",
"network":"192.168.1.0",
"broadcast":"192.168.1.255",
"hostmin":"192.168.1.1",
"hostmax":"192.168.1.254"
}
Notes:
Although IPv6 does not use the concept of networks and broadcasts, the ranges are still needed to do inclusive searches. Also, IPv6 has a subnet segment, but can still be supernetted/subnetted, which this takes into consideration.
