samba - Mar 1998 - Security issue: coul you explain me this netry from log.nmb

hello,

I read this in my ./samba/var/log.nmb

process_node_status_request: status request for name *<00> from IP 
145.72.37.14
on subnet REMOTE_BROADCAST_SUBNET - name not found.

As my subnet is 193.190.195.0, I don't understand this message.

Could help me to understand?

Thanks,
