- 2. Socket Programming • Socket is a IPC (Inter Process Communication) facility for network application. • To make socket communicate with other socket, so it need unique address as a identifier. • Socket Address contain IP Address and Port Number. Example : 192.168.20.12 : 8080 IP Address Port Number

- 6. Internet Addressing • IP is stand for Internet Protocol. • IP is an unique ID. • It use for communicate between 1 point to another point in network. • Public & Private • IPv4 has 32 bits , example : 192.168.32.12 but IP Address is running out….

- 22. Internet Addressing in JAVA • Java is a capable programming language that is capable to support networked environment which support most popular protocol available • Java API that support internet addressing is :- – InetAddress • There are two subclasses under it – Inet4Address – Inet6Address – An InetAddress object is capable to store IP address or Domain name which later used for communication address or translation between the form available.
- 23. IP Addresses & Hostname • Java.net.InetAddress class – Represents a single IP Address – Performs transparent DNS lookups • Java.net.UnknownHostException class – Thrown if DNS system can`t find IP address for specific host
- 24. InetAddress class • Creating an InetAddress object is as follow:- • Some of the useful methods within InetAddress class – getHostName() • It return the host domain name in String format – getHostAddress() • It return the IP address in String format – getLocalHost() • It return InetAddress object with local computer address information with its host name – getByName() • It return InetAddress object of a destination computer containing its address and host name
