     NOTES
     The return value from inet_ntoa() points to a  buffer  which
     is  overwritten on each call.  This buffer is implemented as
     thread-specific data in multithreaded applications.

     the vxworks version of inet_ntoa allocates a buffer for each
     ip address string, and does not reuse the same buffer.

     this is merely to simulate the same behaviour (not multithread
     safe though):
