+The @code{inet_ntoa} function need not be reentrant, and consequently
+is not required to be thread safe.  Implementations of
+@code{inet_ntoa} typically write the time stamp into static buffer.
+If two threads call @code{inet_ntoa} at roughly the same time, you
+might end up with the wrong date in one of the threads, or some
+undefined string.  Further, @code{inet_ntoa} is specific for
+@acronym{IPv4} addresses.
+
+A protocol independent function is @code{inet_ntop}.
