+
+ This class wrapps the standard \c sockaddr_in6 structure. INet6SocketAddress provides access
+ to all members of the sockaddr_in6 structure. Additionally, INet6SocketAddress supports the
+ string representation
+
+ \par "" <tt>[</tt> <i>address</i> [ <tt>\@</tt> <i>interface</i> ] <tt>]:</tt> <i>port</i>
+
+ Where \e address is an arbitrary numeric IPv6 address, \e interface is an optional network
+ interface name and \e port is the port number. The interface specification is only valid if
+ \e address is link-local address. The URL representation of an IPv6 address is as above
+ without the optional interface spec.
+
+ INet6SocketAddress supports conversion constructors from it's string
+ representation. Therefore, wherever a INet6SocketAddress instance is expected, a string may
+ be used instead.
+
+ \implementation The sockaddr_in6 structure has an sin6_flowinfo member. However RFC3493 does
+ not give the use of this field and specifies, that the field should be ignored ... so
+ that's what we do. Furthermore, the GNU libc reference states, that this field is not
+ implemented in the library.
+
+ \implementation We need to return the address in host() by value since we need to return a
+ INet6Address. However, sockaddr_in6 does not have one ...
+
+ \implementation The <tt>char const *</tt> constructor overload is needed to support
+ string-literals where an INet6SocketAddress is expected (the C++ standard does not allow
+ chaining conversion constructors like <tt>char const *</tt> -> \c std::string -> \c
+ INet6SocketAddress)
+
+ \idea Implement a INet6Address_ref class which has an interface identical to INet6Address
+ and is convertible to INet6Address (the latter has a conversion constructor taking the
+ former as arg). This class however references an external in6_addr instead of containing one
+ itself. This can be used in INet6SocketAddress to increase the performance of some
+ operations.
