This class represents a Network Interface address. In short it's an IP address, a subnet mask and a broadcast address when the address is an IPv4 one. An IP address and a network prefix length in the case of IPv6 address.

Inherited Method Summary
Public Methods
public boolean equals (Object obj)
Compares this object against the specified object.
The result is true
if and only if the argument is
not null
and it represents the same interface address as
this object.
Two instances of InterfaceAddress
represent the same
address if the InetAddress, the prefix length and the broadcast are
the same for both.
Parameters
obj | the object to compare against. |
---|
Returns
true
if the objects are the same;false
otherwise.

public InetAddress getAddress ()
Returns an InetAddress
for this address.
Returns
- the
InetAddress
for this address.
public InetAddress getBroadcast ()
Returns an InetAddress
for the broadcast address
for this InterfaceAddress.
Only IPv4 networks have broadcast address therefore, in the case
of an IPv6 network, null
will be returned.
Returns
- the
InetAddress
representing the broadcast address ornull
if there is no broadcast address.
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
short
representing the prefix length for the subnet of that address.
public int hashCode ()
Returns a hashcode for this Interface address.
Returns
- a hash code value for this Interface address.
public String toString ()
Converts this Interface address to a String
. The
string returned is of the form: InetAddress / prefix length [ broadcast address ].
Returns
- a string representation of this Interface address.
