# address.h(3)

Network addresses and sockets related classes.

## NAME

address.h - Network addresses and sockets related classes.

## SYNOPSIS

`#include <cc++/config.h>`\
 `#include <cc++/missing.h>`\
 `#include <cc++/thread.h>`\
 `#include <cc++/exception.h>`\

### Classes

class **ost::IPV4Validator**\
 Classes derived from **IPV4Address** would require an specific validator to pass to the **IPV4Address** constructor.  class **ost::IPV4MulticastValidator**\
 Class for the function object that validates multicast addresses.  class **ost::IPV4Cidr**\
 The CIDR class is used to support routing tables and validate address policies.  class **ost::IPV6Cidr**\
 The CIDR class is used to support routing tables and validate address policies.  class **ost::IPV4Address**\
 The network name and address objects are all derived from a common **IPV4Address** base class.  class **ost::IPV4Mask**\
 Internet addresses used specifically as masking addresses (such as ' 255.255.255.0') are held in the **IPV4Mask** derived object. " class **ost::IPV4Host**\
 This object is used to hold the actual and valid internet address of a specific host machine that will be accessed through a socket.  class **ost::IPV4Broadcast**\
 The broadcast address object is used to store the broadcast address for a specific subnet.  class **ost::IPV4Multicast**\
 A specialization of **IPV4Address** that provides address validation for multicast addresses.  class **ost::IPV6Validator**\
 Classes derived from **IPV6Address** would require an specific validator to pass to the **IPV6Address** constructor.  class **ost::IPV6MulticastValidator**\
 Class for the function object that validates multicast addresses.  class **ost::IPV6Address**\
 The network name and address objects are all derived from a common **IPV6Address** base class.  class **ost::IPV6Mask**\
 Internet addresses used specifically as masking addresses (such as ' 255.255.255.0') are held in the **IPV6Mask** derived object. " class **ost::IPV6Host**\
 This object is used to hold the actual and valid internet address of a specific host machine that will be accessed through a socket.  class **ost::IPV6Broadcast**\
 The broadcast address object is used to store the broadcast address for a specific subnet.  class **ost::IPV6Multicast**\
 A specialization of **IPV6Address** that provides address validation for multicast addresses.
