Java net socket address
Defines channels, which represent connections to entities that are capable of performing I/O operations, such as files and sockets; defines selectors, for multiplexed, non-blocking I/O operations.
Uses of SocketAddress in com.sun.nio.sctp
Returns the source socket address if the message has been received, otherwise the preferred destination of the message to be sent.
Returns all of the remote addresses to which the given association on this channel’s socket is connected.
Uses of SocketAddress in java.net
This class implements an IP Socket Address (IP address + port number) It can also be a pair (hostname + port number), in which case an attempt will be made to resolve the hostname.
Gets the SocketAddress (usually IP address + port number) of the remote host that this packet is being sent to or is coming from.
Sets the SocketAddress (usually IP address + port number) of the remote host to which this datagram is being sent.
Constructs a datagram packet for sending packets of length length with offset ioffset to the specified port number on the specified host.
Constructs a datagram packet for sending packets of length length to the specified port number on the specified host.

Class InetSocketAddress
This class implements an IP Socket Address (IP address + port number) It can also be a pair (hostname + port number), in which case an attempt will be made to resolve the hostname. If resolution fails then the address is said to be unresolved but can still be used on some circumstances like connecting through a proxy.
It provides an immutable object used by sockets for binding, connecting, or as returned values.
The wildcard is a special local IP address. It usually means «any» and can only be used for bind operations.
Constructor Summary
Creates a socket address where the IP address is the wildcard address and the port number a specified value.
Method Summary
Returns the hostname, or the String form of the address if it doesn’t have a hostname (it was created using a literal).
Methods declared in class java.lang.Object
Constructor Details
InetSocketAddress
Creates a socket address where the IP address is the wildcard address and the port number a specified value. A valid port value is between 0 and 65535. A port number of zero will let the system pick up an ephemeral port in a bind operation.
InetSocketAddress
Creates a socket address from an IP address and a port number. A valid port value is between 0 and 65535. A port number of zero will let the system pick up an ephemeral port in a bind operation. A null address will assign the wildcard address.
InetSocketAddress
Creates a socket address from a hostname and a port number. An attempt will be made to resolve the hostname into an InetAddress. If that attempt fails, the address will be flagged as unresolved. If there is a security manager, its checkConnect method is called with the host name as its argument to check the permission to resolve it. This could result in a SecurityException. A valid port value is between 0 and 65535. A port number of zero will let the system pick up an ephemeral port in a bind operation.
Method Details
createUnresolved
Creates an unresolved socket address from a hostname and a port number. No attempt will be made to resolve the hostname into an InetAddress. The address will be flagged as unresolved. A valid port value is between 0 and 65535. A port number of zero will let the system pick up an ephemeral port in a bind operation.
getPort
getAddress
getHostName
Gets the hostname . Note: This method may trigger a name service reverse lookup if the address was created with a literal IP address.
getHostString
Returns the hostname, or the String form of the address if it doesn’t have a hostname (it was created using a literal). This has the benefit of not attempting a reverse lookup.
isUnresolved
toString
Constructs a string representation of this InetSocketAddress. This string is constructed by calling InetAddress.toString() on the InetAddress and concatenating the port number (with a colon). If the address is an IPv6 address, the IPv6 literal is enclosed in square brackets, for example: «localhost/[0:0:0:0:0:0:0:1]:80» . If the address is unresolved, is displayed in place of the address literal, for example «foo/:80» . To retrieve a string representation of the hostname or the address, use getHostString() , rather than parsing the string returned by this toString() method.
equals
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 address as this object. Two instances of InetSocketAddress represent the same address if both the InetAddresses (or hostnames if it is unresolved) and port numbers are equal. If both addresses are unresolved, then the hostname and the port number are compared. Note: Hostnames are case insensitive. e.g. «FooBar» and «foobar» are considered equal.
