Method Detail

isIPv4Address

public static boolean isIPv4Address(java.lang.String input)

Check if input is a valid IPv4 address

The format is 'xxx.xxx.xxx.xxx'. Four blocks of integer numbers ranging from 0 to 255 are required. Letters are not allowed.

Parameters:

input - ip-address to check

Returns:

true if input is in correct IPv4 notation.

isIPv6StdAddress

public static boolean isIPv6StdAddress(java.lang.String input)

Check if the given address is a valid IPv6 address in the standard format

The format is 'xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx'. Eight blocks of hexadecimal digits are required.

Parameters:

input - ip-address to check

Returns:

true if input is in correct IPv6 notation.

isIPv6HexCompressedAddress

public static boolean isIPv6HexCompressedAddress(java.lang.String input)

Check if the given address is a valid IPv6 address in the hex-compressed notation

The format is 'xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx'. If all digits in a block are '0' the block can be left empty.

Parameters:

input - ip-address to check

Returns:

true if input is in correct IPv6 (hex-compressed) notation.

isIPv6Address

public static boolean isIPv6Address(java.lang.String input)

Check if input is a IPv6 address.

Possible notations for valid IPv6 are: - Standard IPv6 address - Hex-compressed IPv6 address - Link-local IPv6 address - IPv4-mapped-to-IPV6 address - IPv6 mixed address

Parameters:

input - ip-address to check

Returns:

true if input is in correct IPv6 notation.

isIPv6MixedAddress

public static boolean isIPv6MixedAddress(java.lang.String input)

Check if the given address is a valid IPv6 address in the mixed-standard or mixed-compressed notation. IPV6 Mixed mode consists of two parts, the first 96 bits (up to 6 blocks of 4 hex digits) are IPv6 the IPV6 part can be either compressed or uncompressed the second block is a full IPv4 address e.g. '0:0:0:0:0:0:172.12.55.18'

Parameters:

input - ip-address to check

Returns:

true if input is in correct IPv6 (mixed-standard or mixed-compressed) notation.

isIPv6IPv4MappedAddress

public static boolean isIPv6IPv4MappedAddress(java.lang.String input)

Check if input is an IPv4 address mapped into a IPv6 address. These are starting with "::fff:" followed by the IPv4 address in a dot-seperated notation.

The format is '::ffff:d.d.d.d'

Parameters:

input - ip-address to check

Returns:

true if input is in correct IPv6 notation containing an IPv4 address

isLinkLocalIPv6WithZoneIndex

public static boolean isLinkLocalIPv6WithZoneIndex(java.lang.String input)

Check if input is a link local IPv6 address starting with "fe80:" and containing a zone index with "%xxx". The zone index will not be checked.

Parameters:

input - ip-address to check

Returns:

true if address part of input is in correct IPv6 notation.

isValidIP

public static boolean isValidIP(java.lang.String ipAddress)

Check if input is a valid IPv4 or IPv6 address.

Parameters:

ipAddress - ip-address to check

Returns:

true if ipAddress is a valid ip-address
