A class describing an IP address

Address constructors

Address()

Create an IPv4 address with the default address: 127001 (loopback)

Address(const PString & dotNotation)

Create an IP address from string notation. eg dot notation x.x.x.x. for IPv4, or colon notation x:x:x::xxx for IPv6

Address(PINDEX len, const BYTE* bytes)

Create an IPv4 or IPv6 address from 4 or 16 byte values

Address(BYTE b1, BYTE b2, BYTE b3, BYTE b4)

Create an IP address from four byte values

Address(DWORD dw)

Create an IPv4 address from a four byte value in network byte order

Address(const in_addr & addr)

Create an IPv4 address from an in_addr structure

Address(const in6_addr & addr)

Create an IPv6 address from an in_addr structure

Create an IP (v4 or v6) address from a sockaddr (sockaddr_in,

Create an IP (v4 or v6) address from a sockaddr (sockaddr_in,

Address& operator=(const in_addr & addr)

Copy an address from another IP v4 address

Address& operator=(const in6_addr & addr)

Copy an address from another IPv6 address

Address& operator=(const PString & dotNotation)

Copy an address from a string

Address& operator=(DWORD dw)

Copy an address from a four byte value in network order

Comparison Compare(const PObject & obj) const

Compare two adresses

PString AsString() const

Format an address as a string

BOOL FromString( const PString & str )

Convert string to IP address. Returns TRUE if was a valid address.

operator PString() const

Format an address as a string

operator in_addr() const

Return IPv4 address in network order

operator in6_addr() const

Return IPv4 address in network order

operator DWORD() const

Return IPv4 address in network order

BYTE Byte1() const

Return first byte of IPv4 address

BYTE Byte2() const

Return second byte of IPv4 address

BYTE Byte3() const

Return third byte of IPv4 address

BYTE Byte4() const

Return fourth byte of IPv4 address

BYTE operator[](PINDEX idx) const

return specified byte of IPv4 or IPv6 address

PINDEX GetSize() const

Get the address length (will be either 4 or 16)

const char* GetPointer() const

Get the pointer to IP address data

unsigned GetVersion() const

Get the version of the IP address being used

BOOL IsValid() const

Check address 0000 or ::

BOOL IsLoopback() const

Check address 127001 or ::1

BOOL IsBroadcast() const

Check for Broadcast address 255255255255

BOOL IsV4Mapped() const

Check for v4 mapped i nv6 address ::ffff:abcd
