169.254.x.x is an adress that a windows machine configured with DHCP assigns by default when it is unable to contact the DHCP server.


I dont think there is any way to identify it.

Hi,


I see it on my logs from PIX. Here is the record:


%PIX-4-106023: Deny udp src outside:169.254.18.31/137 dst inside:172.20.X.X/137 by access-group "FromOutside"


???


I think there is one solution .... to find MAC address....then the switch...then port
