Detailed Description

       The network name and address objects are all derived from a common IPV6Address base class.

       Specific classes, such as IPV4Host, IPV6Mask, etc, are defined from IPV6Address entirely
       so that the manner a network address is being used can easily be documented and understood
       from the code and to avoid common errors and accidental misuse of the wrong address
       object. For example, a 'connection' to something that is declared as a 'IPV6Host' can be
       kept type-safe from a 'connection' accidently being made to something that was declared a
       'IPV6Broadcast'.

Constructor & Destructor Documentation

   ost::IPV6Address::IPV6Address (const IPV6Validator * validator = NULL)
       Create an Internet Address object with an empty (0.0.0.0) address.

Member Function Documentation

   struct in6_addr ost::IPV6Address::getAddress (size_t i) const
       Provide a low level system usable struct in_addr object from the contents of IPV6Address.
       This is needed for services such as bind() and connect().

       Parameters
           i for IPV6Addresses with multiple addresses, returns the address at this index. User
           should call getAddressCount() to determine the number of address the object contains.

       Returns
           system binary coded internet address. If parameter i is out of range, the first
           address is returned.

   struct in6_addr ost::IPV6Address::getAddress (void) const
       Provide a low level system usable struct in_addr object from the contents of IPV6Address.
       This is needed for services such as bind() and connect().

       Returns
           system binary coded internet address.

   size_t ost::IPV6Address::getAddressCount () const [inline]
       Returns the number of internet addresses that an IPV6Address object contains. This usually
       only happens with IPV6Host objects where multiple IP addresses are returned for a DNS
       lookup

   const char* ost::IPV6Address::getHostname (void) const
       Provide a string representation of the value (Internet Address) held in the IPV6Address
       object.

       Returns
           string representation of IPV6Address.

   bool ost::IPV6Address::isInetAddress (void) const
       May be used to verify if a given IPV6Address returned by another function contains a
       'valid' address, or '0.0.0.0' which is often used to mark 'invalid' IPV6Address values.

       Returns
           true if address != 0.0.0.0.

   bool ost::IPV6Address::operator! () const [inline]
   bool ost::IPV6Address::operator!= (const IPV6Address & a) const
       Compare two internet addresses to see if they are not equal (if they each refer to unique
       and different physical ip addresses). This is implimented in terms of operator==

   IPV6Address& ost::IPV6Address::operator= (const char * str)
   IPV6Address& ost::IPV6Address::operator= (const IPV6Address & rhs)
   IPV6Address& ost::IPV6Address::operator= (struct in6_addr addr)
   bool ost::IPV6Address::operator== (const IPV6Address & a) const
       Compare two internet addresses to see if they are equal (if they specify the physical
       address of the same internet host). If there is more than one IP address in either
       IPV6Address object, this will return true if all of the IP addresses in the smaller are in
       the larger in any order.

   void ost::IPV6Address::setAddress (const char * host) [protected]
       Used to specify a host name or numeric internet address.

       Parameters
           host The string representation of the IP address or a hostname, , if NULL, it will
           default to INADDR_ANY

   bool ost::IPV6Address::setIPAddress (const char * host) [protected]
       Sets the IP address from a string representation of the numeric address, ie '127.0.0.1'.

       Parameters
           host The string representation of the IP address

       Returns
           true if successful
