+PRIPv6Addr
+==========
+
+Type used in the ``ipv6.ip`` field of the :ref:`PRNetAddr` structure.
+
+
+Syntax
+------
+
+.. code::
+
+   #include <prio.h>
+
+   #if defined(_PR_INET6)
+      typedef struct in6_addr PRIPv6Addr;
+   #endif /* defined(_PR_INET6) */
+
+
+Description
+-----------
+
+PRIPv6Addr represents a 128-bit IPv6 address. It is equivalent to struct
+``in6_addr`` in the Berkeley socket interface. :ref:`PRIPv6Addr` is always
+manipulated as a byte array. Unlike the IPv4 address (a 4-byte unsigned
+integer) or the port number (a 2-byte unsigned integer), it has no
+network or host byte order.
