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}.
