Constant	Value	Description	Defined By
IPV4	4		yii\helpers\BaseIpHelper
IPV4_ADDRESS_LENGTH	32	The length of IPv4 address in bits	yii\helpers\BaseIpHelper
IPV6	6		yii\helpers\BaseIpHelper
IPV6_ADDRESS_LENGTH	128	The length of IPv6 address in bits	yii\helpers\BaseIpHelper

expandIPv6() public static method

Expands an IPv6 address to it's full notation.

For example 2001:db8::1 will be expanded to 2001:0db8:0000:0000:0000:0000:0000:0001

public static string expandIPv6 ( $ip )
$ip	string	The original valid IPv6 address
return	string	The expanded IPv6 address

getIpVersion() public static method

Gets the IP version. Does not perform IP address validation.

public static integer getIpVersion ( $ip )
$ip	string	The valid IPv4 or IPv6 address.
return	integer	IPV4 or IPV6

inRange() public static method

Checks whether IP address or subnet $subnet is contained by $subnet.

For example, the following code checks whether subnet 192.168.1.0/24 is in subnet 192.168.0.0/22:

IpHelper::inRange('192.168.1.0/24', '192.168.0.0/22'); // true

In case you need to check whether a single IP address 192.168.1.21 is in the subnet 192.168.1.0/24, you can use any of theses examples:

IpHelper::inRange('192.168.1.21', '192.168.1.0/24'); // true
IpHelper::inRange('192.168.1.21/32', '192.168.1.0/24'); // true

public static boolean inRange ( $subnet, $range )
$subnet	string	The valid IPv4 or IPv6 address or CIDR range, e.g.: `10.0.0.0/8` or `2001:af::/64`
$range	string	The valid IPv4 or IPv6 CIDR range, e.g. `10.0.0.0/8` or `2001:af::/64`
return	boolean	Whether $subnet is contained by $range
throws	yii\base\NotSupportedException

ip2bin() public static method

Converts IP address to bits representation.

public static string ip2bin ( $ip )
$ip	string	The valid IPv4 or IPv6 address
return	string	Bits as a string
throws	yii\base\NotSupportedException
