It just dawned on me that you are connected to your ISP when you see
this, and those packets are probably coming from someone _else_ (you
were probably not 129dial.supernet.kz when you saw these).  Depending
on your ISP's network configuration, you may see multicast and
broadcast packets generated by other users.  Generally harmless.
