Using ntop I could find 2 IP addresses for the MAC of the modem router:
The gateway (192.168.1.1) and 10.39.191.254.
I think this IP address is local to the ISP network.

Now, why the ping caused that strange message if the host name is in the
hosts files of all PCs in my network? Besides this message began to
occur only recently.

Anyway, knowing what this address is no longer exists any security
problem I was afraid of.

Thanks to all who responded.
