This is a bit speculative, though, as I haven't traced this particular interaction through the source code. Some platforms are capable of sending both raw Ethernet and raw IP packets, and forcing Ethernet frame building with -send-eth may lock in one MAC address and ensure that responses from the other one are not registered. You may be able to force one or the other result by using the -send-eth option. Since the OS detection phase runs later than the port scan phase, it would seem that those probes (sent mostly to open ports) are getting different responses than the last probes sent in the port scan phase. This is a very unusual circumstance, though, since the target MAC would be the same in each instance. This means that if different probes receive different responses, a different MAC address might be reported. one that is likely to have come from the target) is received and has a MAC address in it, the address is recorded.

Many systems and network administrators also find it useful for tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime.Nmap uses packet sniffing to detect responses to its probes for host discovery, port scanning, and OS discovery. Nmap ("Network Mapper") is a free and open source (license) utility for network discovery and security auditing. Once you have identified the MAC addresses that you wish to scan, feed the corresponding IP addresses to nmap for scanning.
You can use ARP to resolve the IP addresses (Obtained during host discovery) to MAC addresses (Assuming its all in the same local area network). This step will give you a list of active IP addresses. Of course this does not make port scanning illegal. Based on the information that you have provided, I would suggest using nmap to perform a host discovery i.e. After all, no United States federal laws explicitly criminalize port scanning. Nmap done: 256 IP addresses (7 hosts up) scanned in 9.
MAC Address: 00:17:88:29:80:3F (Philips Lighting BV) There are a few ways to figure out the device thats using the MAC address. MAC Address: 50:DD:FF:AA:DD:BA (Tp-link Technologies) Nmap scan report for f3d0r4.lan (192.168.0.165) Host is up. And if you know the MAC address you can also do this to determine the device thats using it. While civil and (especially) criminal court cases are the nightmare scenario for Nmap users, these are very rare. MAC Address: 40:DD:DD:8F:FF:F5 (Asustek Computer) Nmap scan report for TL-WPA4220.lan (192.168.0.225) Host is up (0.61s latency).

To install NMAP on Ubuntu, run the command: sudo apt-get install nmap. This command is commonly refereed to as a ping scan, and tells nmap to send an icmp echo request, TCP SYN to port 443, TCP ACK to port 80 and icmp timestamp request to all hosts in the specified subnet. This is one of the simplest uses of nmap. Make sure the software packages on your Ubuntu system are up-to-date with the command: sudo apt-get update. Nmap scan report for 192.168.0.110 Host is up (0.0018s latency). One may also ask, how do I download Nmap on Ubuntu?
