static byte [] createByteArrayFromIPAddressString

(

String

ipAddressString

)

[static]

Creates an byte[] based on an ipAddressString.

No error handling is performed here.

(

byte

ipByteArray[]

)

[static]

static void convertToBytes	(	String	hexWord,
		byte	ipByteArray[],
		int	byteIndex
	)			[static]

Converts a 4 character hex word into a 2 byte word equivalent.

static int getIntValue

(

char

c

)

[static, package]

static boolean isIPv4MappedAddress

(

byte

ipAddress[]

)

[static, private]

static int bytesToInt	(	byte	bytes[],
		int	start
	)			[static]

Takes the byte array and creates an integer out of four bytes starting at start as the high-order byte.

This method makes no checks on the validity of the parameters.

static String addressToString

(

int

value

)

[static]

static boolean isValidIP6Address

(

String

ipAddress

)

[static]

static boolean isValidIP4Word

(

String

word

)

[static]

static boolean isValidHexChar

(

char

c

)

[static, package]

static boolean isValidIPV4Address

(

String

value

)

[static]

Takes a string and parses it to see if it is a valid IPV4 address.

Returns:

true, if the string represents an IPV4 address in dotted notation, false otherwise
