IP Operations

$ip = new IP('192.168.1.1');
echo $ip->version;// IPv4

$ip = new IP('fc00::');
echo $ip->version; // IPv6

Parsing IP from integer, binary and hex representation:

echo (string)IP::parse(2130706433); // 127.0.0.1
echo (string)IP::parse('0b11000000101010000000000100000001') // 192.168.1.1
echo (string)IP::parse('0x0a000001'); // 10.0.0.1

or:

echo (string)IP::parseLong(2130706433); // 127.0.0.1
echo (string)IP::parseBin('11000000101010000000000100000001'); // 192.168.1.1
echo (string)IP::parseHex('0a000001'); // 10.0.0.1

Converting IP to other formats:

echo IP::parse('192.168.1.1')->bin // 11000000101010000000000100000001
echo IP::parse('10.0.0.1')->hex // 0a000001
echo IP::parse('127.0.0.1')->long // 2130706433

###Other public properties:###

maxPrefixLength The max number of bits in the address representation: 32 for IPv4, 128 for IPv6.

bitsInOctet The count of bits in one octet of address representation: 8 for IPv4, 16 for IPv6

reversePointer The name of the reverse DNS PTR for the address:

echo new IP::parse('192.0.2.5')->reversePointer // 5.2.0.192.in-addr.arpa
echo new IP::parse('2001:db8::567:89ab')->reversePointer // b.a.9.8.7.6.5.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.8.b.d.0.1.0.0.2.ip6.arpa

Networking

$network = new Network(new IP('192.168.1.1'), new IP('255.255.255.0'));
print_r($network->info);

echo Network::parse('192.0.0.1 255.0.0.0')->CIDR; // 192.0.0.0/8

echo (string)Network::parse('192.0.0.1'); // 192.0.0.1/32

Iterate over Network`s Host-IPs:

$network = Network::parse('192.168.1.0/24');
foreach($network as $ip) {
	echo (string)$ip . '<br>';
}

192.168.1.1
...
192.168.1.254

Excluding IP from Network:

$excluded = Network::parse('192.0.0.0/8')->exclude(new IP('192.168.1.1'));
foreach($excluded as $network) {
	echo (string)$network . '<br>';
}

192.0.0.0/9
192.128.0.0/11
192.160.0.0/13
192.168.0.0/24
192.168.1.0/32
192.168.1.2/31
...
192.192.0.0/10

Excluding Subnet from Network:

$excluded = Network::parse('192.0.0.0/8')->exclude(new Network('192.168.1.0/24'));
foreach($excluded as $network) {
	echo (string)$network . '<br>';
}

Count of Host-IPs

echo count(Network::parse('192.168.1.0/24')) // 254

Range Operations

Defining a range in different formats:

$range = new Range(new IP('192.168.1.0'), new IP('192.168.1.255'));
$range = Range::parse('192.168.1.0-192.168.1.255');
$range = Range::parse('192.168.1.*');
$range = Range::parse('192.168.1.0/24');

Check if IP is within Range:

echo Range::parse('192.168.1.1-192.168.1.254')->contains(new IP('192.168.1.5')); // true
echo Range::parse('::1-::ffff')->contains(new IP('::1234')); // true

Iterating over Range IPs:

$range = Range::parse('192.168.1.1-192.168.1.254');
foreach($range as $ip) {
	echo (string)$ip . '<br>';
}

192.168.1.1
...
192.168.1.254

Get Networks that fit into a specified range of IPs:

$networks = Range::parse('192.168.1.1-192.168.1.254')->getNetworks();

foreach($networks as $network) {
	echo (string)$network . '<br>';
}

Count of IPs in Range

echo count(Range::parse('192.168.1.1-192.168.1.254')) // 254
