Method Detail

getMyLinkLocalAddress

public static byte[] getMyLinkLocalAddress(IEEEAddress addr)

getMyLinkLocalAddress

protected static byte[] getMyLinkLocalAddress(byte[] linkAddress)

A routine to create an Inet6Address with our link local address

Returns:

The link local address of this node in Inet6Address format

getNetworkPart

public static byte[] getNetworkPart(byte[] addr,
                                    int bits)

parseInet6Address

public static Inet6Address parseInet6Address(String address)

parseInet6Netmask

public static int parseInet6Netmask(String address)

createNetmask

public static byte[] createNetmask(int bits)

equals

public static boolean equals(byte[] arr1,
                             byte[] arr2)

compare

public static int compare(byte[] ipaddress,
                          byte[] test)

hex8

public static String hex8(int data)

hex16

public static String hex16(int data)

isMC

public static boolean isMC(byte[] ipaddress)

Utility routine to check if the address is a multicast.

Returns:

a boolean indicating if the address is a multicast address, false if it is not not a multicast address

isGlobal

public static boolean isGlobal(byte[] ipaddress)

Utility routine to check if the address is a multicast.

Returns:

a boolean indicating if the address is a globally routable address, false if it is not not a multicast address

isMCLinkLocal

public static boolean isMCLinkLocal(byte[] ipaddress)

Utility routine to check if the multicast address has link scope.

Returns:

a boolean indicating if the address has is a multicast address of link-local scope, false if it is not of link-local scope or it is not a multicast address

isLinkLocalAddress

public static boolean isLinkLocalAddress(byte[] ipaddress)

Utility routine to check if the InetAddress is an link local address.

Returns:

a boolean indicating if the InetAddress is a link local address; or false if address is not a link local unicast address.

isAnyLocalAddress

public static boolean isAnyLocalAddress(byte[] ipaddress)

Utility routine to check if the InetAddress in a wildcard address.

Returns:

a boolean indicating if the Inetaddress is a wildcard address.

isLoopbackAddress

public static boolean isLoopbackAddress(byte[] ipaddress)

Utility routine to check if the InetAddress is a loopbackAddress address.

Returns:

a boolean indicating if the InetAddress is a loopbackAddress address; or false otherwise.

isMulticastAddress

public static boolean isMulticastAddress(byte[] ipaddress)

Utility routine to check if the InetAddress is an IP multicast address. 11111111 at the start of the address identifies the address as being a multicast address.

Returns:

a boolean indicating if the InetAddress is an IP multicast address

addressToString

public static String addressToString(byte[] address)

macAddressToEUI64
