48 /** \brief IPv4 socket address
50 INet4Address wraps the standard sockaddr_in datatype. It provides simple accessor methods
51 to access the host and port. It does \e not integrate \c gethostbyname or DNS lookup.
53 \implementation This implementation is based on sockaddr_in, which is needed since it needs
54 to provide a non-const struct sockaddr * for legacy compatibility.

112 /** \brief IPv6 socket address
114 This class wraps the standard \c sockaddr_in6 structure. INet6SocketAddress provides access
115 to all members of the sockaddr_in6 structure. Additionally, INet6SocketAddress supports the
116 string representations
119 <tt>[</tt> <i>address</i> [ <tt>%</tt> <i>zone-id</i> ] <tt>]:</tt> <i>port</i> \n
120 <i>hostname</i> <tt>:</tt> <i>port</i>
122 Where \e address is an arbitrary numeric IPv6 address, \e zone-id is an optional network
123 interface name and \e port is the port number. So some example addresses are
126 <tt>[2001:db8:1::1]:80</tt> \n
127 <tt>www.6bone.net:80</tt> \n
128 <tt>[fe80::1\%eth0]:443</tt>
130 \implementation The sockaddr_in6 structure has an sin6_flowinfo member. However RFC3493 does
131 not give the use of this field and specifies, that the field should be ignored ... so
132 that's what we do. Furthermore, the GNU libc reference states, that this field is not
133 implemented in the library.
135 \idea Implement a INet6Address_ref class which has an interface identical to INet6Address
136 and is convertible to INet6Address (the latter has a conversion constructor taking the
137 former as arg). This class however references an external in6_addr instead of containing
138 one itself. This can be used in INet6SocketAddress to increase the performance of some
