advanced ip scanner not showing mac address

If your remote network's router supports SNMP, this can be configured to pull IP-to-MAC address mappings from that router. This may work across router, but you would need to have access to the remote PCs WMI.

The WMI query method connects to the WMI subsystem on the target computer and analyses the Win32_NetworkAdapterConfiguration class to find out its MAC address.

This works across routers, but only with the PCs that support it - that the 5% MAC addresses you do see. If the target device responds to the request, the response will contain the MAC address of that device.

The NetBios query method sends a NetBios packet to the target device.

The ARP query method sends an ARP packet to the target device to resolve its MAC address directly.

We employ a few methods related to MAC address resolution as can be seen in the application:

You can see this mentioned in this 'Getting IP and MAC address from behind a router' discussion. In order to avoid the detection process itself being detected, typically tools will avoid sending mass amounts of ICMP packets that clearly show anyone monitoring the network the intentions of the attacker but instead try other methods (such as attempting connections on well-known ports).It's exactly that: MAC addresses by design do not get passed across routers or VPNs (ARP protocol messages are not exchanged across). The third thing that may be happening is that it is not a standard ICMP ping being used to detect hosts and the remote firewall is blocking detection. You may have been scanning on an interface that only contains your machine (maybe a virtual interface). This network range may have been detected by looking at the interface address as it can be calculated from the machine's IP and the netmask.

Typically a home network will go from 192.168.1.1 to 192.168.1.254 which can also be represented as 192.168.1.0/24 in CIDR format. If you've specified this yourself, you may have specified it incorrectly. It is not really feasible to ping every possible address in order to discover machines, hence the address range of your local network must be known. There are a few things that might be happening here.
