Detailed Description

Represents an IP address.

Constructor & Destructor Documentation

IPAddress() [1/7]

IPAddress::IPAddress ( )

noexcept

Creates a null address - 0.0.0.0 (IPv4) or ::, (IPv6)

IPAddress() [2/7]

IPAddress::IPAddress ( const uint8 * bytes, bool IPv6 = false )

explicitnoexcept

Creates an IPv4 or IPv6 address by reading 4 or 16 bytes from an array.

Parameters

bytes	The array containing the bytes to read.
IPv6	if true indicates that 16 bytes should be read instead of 4.

IPAddress() [3/7]

IPAddress::IPAddress ( const uint16 * bytes )

explicitnoexcept

Creates an IPv6 address from an array of 8 16-bit integers.

Parameters

bytes

The array containing the bytes to read.

IPAddress() [4/7]

IPAddress::IPAddress ( uint8 address1, uint8 address2, uint8 address3, uint8 address4 )

noexcept

Creates an IPv4 address from 4 bytes.

IPAddress() [5/7]

IPAddress::IPAddress ( uint16 address1, uint16 address2, uint16 address3, uint16 address4, uint16 address5, uint16 address6, uint16 address7, uint16 address8 )

noexcept

Creates an IPv6 address from 8 16-bit integers.

IPAddress() [6/7]

IPAddress::IPAddress ( uint32 asNativeEndian32Bit )

explicitnoexcept

Creates an IPv4 address from a packed 32-bit integer, where the MSB is the first number in the address, and the LSB is the last.

IPAddress() [7/7]

IPAddress::IPAddress ( const String & address )

explicit

Parses a string IP address of the form "1.2.3.4" (IPv4) or "1:2:3:4:5:6:7:8" (IPv6).

Member Function Documentation

any()

static IPAddress IPAddress::any ( )

staticnoexcept

Returns an IP address meaning "any", equivalent to 0.0.0.0 (IPv4) or ::, (IPv6)

broadcast()

static IPAddress IPAddress::broadcast ( )

staticnoexcept

Returns an IPv4 address meaning "broadcast" (255.255.255.255)

local()

static IPAddress IPAddress::local ( bool IPv6 = false )

staticnoexcept

Returns an IPv4 or IPv6 address meaning "localhost", equivalent to 127.0.0.1 (IPv4) or ::1 (IPv6)

findAllAddresses()

static void IPAddress::findAllAddresses ( Array< IPAddress > & results, bool includeIPv6 = false )

static

Populates a list of all the IP addresses that this machine is using.

getAllAddresses()

static Array< IPAddress > IPAddress::getAllAddresses ( bool includeIPv6 = false )

static

Populates a list of all the IP addresses that this machine is using.

getLocalAddress()

static IPAddress IPAddress::getLocalAddress ( bool includeIPv6 = false )

static

Returns the first 'real' address for the local machine.

Unlike local(), this will attempt to find the machine's actual assigned address rather than "127.0.0.1". If there are multiple network cards, this may return any of their addresses. If it doesn't find any, then it'll return local() as a fallback.

isNull()

bool IPAddress::isNull

(

)

const

Returns whether the address contains the null address (e.g.

0.0.0.0).

toString()

String IPAddress::toString

(

)

const

Returns a dot- or colon-separated string in the form "1.2.3.4" (IPv4) or "1:2:3:4:5:6:7:8" (IPv6).

compare()

int IPAddress::compare ( const IPAddress & ) const

noexcept

Compares this IPAddress with another.

Returns

0 if the two addresses are identical, negative if this address is smaller than the other one, or positive if is greater.

operator==()

bool IPAddress::operator== ( const IPAddress & ) const

noexcept

operator!=()

bool IPAddress::operator!= ( const IPAddress & ) const

noexcept

operator<()

bool IPAddress::operator< ( const IPAddress & ) const

noexcept

operator>()

bool IPAddress::operator> ( const IPAddress & ) const

noexcept

operator<=()

bool IPAddress::operator<= ( const IPAddress & ) const

noexcept

operator>=()

bool IPAddress::operator>= ( const IPAddress & ) const

noexcept

getFormattedAddress()

static String IPAddress::getFormattedAddress ( const String & unformattedAddress )

static

Returns a formatted version of the provided IPv6 address conforming to RFC 5952 with leading zeros suppressed, lower case characters, and double-colon notation used to represent contiguous 16-bit fields of zeros.

Parameters

unformattedAddress

the IPv6 address to be formatted

isIPv4MappedAddress()

static bool IPAddress::isIPv4MappedAddress ( const IPAddress & mappedAddress )

static

Returns true if the given IP address is an IPv4-mapped IPv6 address.

convertIPv4MappedAddressToIPv4()

static IPAddress IPAddress::convertIPv4MappedAddressToIPv4 ( const IPAddress & mappedAddress )

static

Converts an IPv4-mapped IPv6 address to an IPv4 address.

If the address is not IPv4-mapped, this will return a null address.

convertIPv4AddressToIPv4Mapped()

static IPAddress IPAddress::convertIPv4AddressToIPv4Mapped ( const IPAddress & addressToMap )

static

Converts an IPv4 address to an IPv4-mapped IPv6 address.

getInterfaceBroadcastAddress()

static IPAddress IPAddress::getInterfaceBroadcastAddress ( const IPAddress & interfaceAddress )

static

If the IPAdress is the address of an interface on the machine, returns the associated broadcast address.

If the address is not an interface, it will return a null address.
