checkIPv6 [line 646]

boolean checkIPv6(
string
$ip)

Checks an IPv6 adress

Checks if the given IP is IPv6-compatible

Return: true if $ip is an IPv6 adress
Access: public

Parameters:

string $ip — a valid IPv6-adress

[ Top ]

compress [line 527]

string compress(
string
$ip)

Compresses an IPv6 adress

RFC 2373 allows you to compress zeros in an adress to '::'. This function expects an valid IPv6 adress and compresses successive zeros to '::'

Example: FF01:0:0:0:0:0:0:101 -> FF01::101 0:0:0:0:0:0:0:1 -> ::1

Return: the compressed IPv6-adress (hex format)
Author: elfrink at introweb dot nl
See: Uncompress()
Access: public

Parameters:

string $ip — a valid IPv6-adress (hex format)

[ Top ]

getAddressType [line 324]

int getAddressType(
String
$ip)

Returns the type of an IPv6 address.

RFC 1883, Section 2.3 describes several types of addresses in the IPv6 addresse space. Several addresse types are markers for reserved spaces and as consequence a subject to change.

Return: one of the addresse type constants

Since: 1.1.0
Access: public

Parameters:

String $ip — the IP address in Hex format, compressed IPs are allowed

getNetmask [line 194]

String getNetmask(
String
$ip, [int
$bits = null])

Calculates the network prefix based on the netmask bits.

Return: the network prefix
Since: 1.1.0
Access: public

Parameters:

String	`$ip`	—	the (compressed) IP in Hex format
int	`$bits`	—	if the number of netmask bits is not part of the IP you must provide the number of bits

[ Top ]

getNetmaskSpec [line 160]

String getNetmaskSpec(
String
$ip)

Returns a possible existing netmask specification at an IP addresse.

Return: the netmask spec
Since: 1.1.0
Access: public

Parameters:

String $ip — the (compressed) IP as Hex representation

[ Top ]

getPrefixLength [line 727]

Mixed getPrefixLength(
String
$ip)

Tests for a prefix length specification in the address and returns the prefix length, if exists

Return: the prefix as String or false, if no prefix was found
Access: public

Parameters:

String $ip — a valid ipv6 address

[ Top ]

isInNetmask [line 244]

boolean isInNetmask(
String
$ip, String
$netmask, [int
$bits = null])

Checks if an (compressed) IP is in a specific address space.

IF the IP does not contains the number of netmask bits (F8000::FFFF/16) then you have to use the $bits parameter.

Return: true if $ip is in the netmask
Since: 1.1.0
Access: public

Parameters:

String	`$ip`	—	the IP to check (eg. F800::FFFF)
String	`$netmask`	—	the netmask (eg F800::)
int	`$bits`	—	the number of netmask bits to compare, if not given in $ip

[ Top ]

parseAddress [line 792]

Array parseAddress(

$ipToParse, [String
$bits = null], String
$ip)

Returns the lowest and highest IPv6 address for a given IP and netmask specification

The netmask may be a part of the $ip or the number of netwask bits is provided via $bits

The result is an indexed array. The key 'start' contains the lowest possible IP adress. The key 'end' the highest address.

Return: ['start', 'end'] the lowest and highest IPv6 address
Author: Nicholas Williams
Access: public

Parameters:

String	`$ip`	—	the IPv6 address
String	`$bits`	—	the optional count of netmask bits
	`$ipToParse`	—

[ Top ]

removeNetmaskSpec [line 131]

String removeNetmaskSpec(
String
$ip)

Removes a possible existing netmask specification at an IP addresse.

Return: the IP without netmask length
Since: 1.1.0
Access: public

Parameters:

String $ip — the (compressed) IP as Hex representation

[ Top ]

removePrefixLength [line 755]

String removePrefixLength(
String
$ip)

Tests for a prefix length specification in the address and removes the prefix length, if exists

Return: the address without a prefix length
Access: public

Parameters:

String $ip — a valid ipv6 address

[ Top ]

SplitV64 [line 608]

array SplitV64(
string
$ip, [
$uncompress = true])

Splits an IPv6 adress into the IPv6 and a possible IPv4 part

RFC 2373 allows you to note the last two parts of an IPv6 adress as an IPv4 compatible adress

Example: 0:0:0:0:0:0:13.1.68.3 0:0:0:0:0:FFFF:129.144.52.38

Return: [0] contains the IPv6 part, [1] the IPv4 part (hex format)
Access: public

Parameters:

string	`$ip`	—	a valid IPv6-adress (hex format)
	`$uncompress`	—

[ Top ]

uncompress [line 407]

string uncompress(
string
$ip)

Uncompresses an IPv6 adress

RFC 2373 allows you to compress zeros in an adress to '::'. This function expects an valid IPv6 adress and expands the '::' to the required zeros.

Example: FF01::101 -> FF01:0:0:0:0:0:0:101 ::1 -> 0:0:0:0:0:0:0:1

Return: the uncompressed IPv6-adress (hex format)
See: Compress()
Access: public

Parameters:

string $ip — a valid IPv6-adress (hex format)
