Hi,

I think it shows you default route address.

But you can do one thing, by using Sniffer you can check out MAC addesss -> IP address.

0.0.0.0 is belongs to source IP address.

Source IP address for the DSG stream. If an asterisk (*) appears as the source IP address, it indicates that the source IP address is 0.0.0.0, which allows any IP address as the source IP address.
