Hello All,

I have been seeing "a lot" of these lately, could anybody offer any
suggestions to what this may be.  I have searched for "" and
port 57989, but did not find much supporting material.  The destination IP
does not accept connections on port 57989.  I am not too worried as there
is no payload in the packets, but would like you thoughts.

Best Regards,
