Simply stated, a computers own hardware configuration determines its MAC address while the configuration of the network it is connected to determines its IP address. These two addresses originate from different sources. For example, ipconfig is useful for getting information on network interfaces, while the arp command is useful for running a quick sweep of all the devices on your network.įor more options in macOS, learn how to install it on a USB drive. It is usually not possible for a person to get the MAC address of a computer from its IP address alone.
While nmap is certainly one of the most powerful network tools available, it isn’t the only software you’ll want in your toolset. For more information, see the nmap manual. Is this all nmap can do?Ĭovering everything nmap could do would take several articles. In addition to macOS, nmap is also available on Windows, Linux, and other Unix variants like FreeBSD, Solaris, and more. While installing with the brew command is easy, you can also install nmap with the macOS installer from the nmap website. There is nothing wrong with using it, especially if you’re using it on your own network. While nmap can be used for nefarious purposes, there is nothing about nmap that makes it a hacking tool by itself. You can run arp -a -i en0 to only get reports from your network interface en0, but that’s all.
