If you ever need to exclude certain IPs from the IP range scan, you can use the “–exclude” option, as you see below: You can even use wildcards to scan the entire C class IP range, for example: This will scan 14 consecutive IP ranges, from 8.8.8.1 to 8.8.8.14.Īn alternative is to simply use this kind of range: You can also use Nmap to scan entire CIDR IP ranges, for example:
You can also scan consecutive IP addresses: Nmap is able to scan all possible ports, but you can also scan specific ports, which will report faster results. In this example, we scanned all 65535 ports for our localhost computer. Scan specific ports or scan entire port ranges on a local or remote server These kinds of basic scans are perfect for your first steps when starting with Nmap. Now, if you want to scan a hostname, simply replace the IP for the host, as you see below: Let’s get to know a few useful command-line based scans that can be performed using Nmap. It was mentioned in the Top 20 OSINT Tools article we published, and today we’ll explore a little bit more about this essential security tool with some practical terminal-based Nmap commands. After making an attempt to contact an IP address (either using Nmap or some other tool like ping), run arp -n to print the table of IP-to-MAC address mappings. Fortunately, there are other sources of MAC address information on a Linux system: the system's ARP tables. Nmap must be run as root in order to retrieve this information. Run it as root or with sudo so that nmap can send raw packets in order to get remote MAC. Nmap done: 256 IP addresses (3 hosts up) scanned in 2.71 seconds :$. Refer this for more information on using nmap. In short: Host Discovery IP to MAC conversion Identify target IP addresses using MAC Port scanning. Once you have identified the MAC addresses that you wish to scan, feed the corresponding IP addresses to nmap for scanning.
