Class NetworkInterface
java.lang.Objectjava.net.NetworkInterface
- public final class NetworkInterface
- extends java.lang.Object
This class models a network interface on the host computer. A network interface contains a name (typically associated with a specific hardware adapter) and a list of addresses that are bound to it. For example, an ethernet interface may be named "eth0" and have the address 192.168.1.101 assigned to it.

getName
public java.lang.String getName()
- Returns the name of the network interface
getInetAddresses
public java.util.Enumeration getInetAddresses()
- Returns all available addresses of the network interface
If a @see SecurityManager is available all addresses are checked
with @see SecurityManager::checkConnect() if they are available.
Only
InetAddressesare returned where the security manager doesn't throw an exception.
getDisplayName

- Returns the display name of the interface
getByName
public static NetworkInterface getByName(java.lang.String name) throws SocketException
- Returns an network interface by name
getByInetAddress
public static NetworkInterface getByInetAddress(InetAddress addr) throws SocketException
- Return a network interface by its address
condense
private static java.util.Collection condense(java.util.Collection interfaces)
getNetworkInterfaces
public static java.util.Enumeration getNetworkInterfaces() throws SocketException
- Return an
Enumerationof all available network interfaces
equals
public boolean equals(java.lang.Object obj)
- Checks if the current instance is equal to obj
hashCode
public int hashCode()
- Returns the hashcode of the current instance
