Concepts

InetAddress

https://docs.oracle.com/javase/8/docs/api/java/net/InetAddress.html

This class represents an Internet Protocol (IP) address. Its subclasses represent either 32 bit IPv4 addresses (Inet4Address) or an 128 bit IPv6 addresses (Inet6Address)

Inet4Address

https://docs.oracle.com/javase/8/docs/api/java/net/Inet4Address.html

Inet6Address

https://docs.oracle.com/javase/8/docs/api/java/net/Inet6Address.html

SocketAddress

https://docs.oracle.com/javase/8/docs/api/java/net/SocketAddress.html

Is an immutable representation of a socket address. It does not have any association with any protocol. The values are used by sockets for binding, connecting or as returned values.

InetSocketAddress

https://docs.oracle.com/javase/8/docs/api/java/net/InetSocketAddress.html

Represents an IP socket address (IP address + port or hostname + port).

NetworkInterface

https://docs.oracle.com/javase/8/docs/api/java/net/NetworkInterface.html

The representation of a network interface available on the host. It is identified by a name, the same name returned by ifconfig -a, if the host runs a Unix system.

The instance can be used to get the list of addresses associated with the interface.
