1.Sometimes I use "nbtstat -A A.B.C.D" , then I cannot find NETBIOS name for some machines. why ? Suppose , I use "nbtstat -A 192.168.1.20" , and 192.168.1.20 is static ip addres not DHCP address. And Then I cannot solve this name even if it's on Windows platform . Why ?
2. Can I ping MAC address instead of IP address?
