Method Details
-
getAddress
Returns anInetAddress
for this address.- Returns:
- the
InetAddress
for this address.
-
getBroadcast
Returns anInetAddress
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.
-
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
short
representing the prefix length for the subnet of that address.
-
equals
Compares this object against the specified object. The result istrue
if and only if the argument is notnull
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. -
