Class InterfaceAddress
java.lang.Object
java.net.InterfaceAddress
This class represents a Network Interface address. In the case of
IPv4, this comprises the IP address, a subnet mask, and a broadcast
address if the interface supports broadcast. In the case of IPv6,
it comprises the IP address and a network prefix length.

Method Details
-
getAddress
Returns anInetAddressfor this address.- Returns:
- the
InetAddressfor this address.
-
getBroadcast
Returns anInetAddressfor the broadcast address for this InterfaceAddress.Only IPv4 networks have broadcast address therefore, in the case of an IPv6 network,
nullwill be returned.Certain network interfaces, such as the loopback interface, do not support broadcasting and will also return
null.- Returns:
- the
InetAddressrepresenting the broadcast address ornullif there is no broadcast address.
-
getNetworkPrefixLength
public short getNetworkPrefixLength()Returns the network prefix length for this address. This is also known as the subnet mask in the context of IPv4 addresses. Typical IPv4 values would be 8 (255.0.0.0), 16 (255.255.0.0) or 24 (255.255.255.0).Typical IPv6 values would be 128 (::1/128) or 10 (fe80::203:baff:fe27:1243/10)
- Returns:
- a
shortrepresenting the prefix length for the subnet of that address.
-
equals
Compares this object against the specified object. The result istrueif and only if the argument is notnulland it represents the same interface address as this object.Two instances of
InterfaceAddressrepresent the same address if the InetAddress, the prefix length and the broadcast are the same for both. -
