NMap 4.75 now maps the network graphically

September 11, 2008 – 5:50 AM

Nmap, the popular network scanner and mapper, has been updated to version 4.75 and gained the ability to graphically display the network topology it scans and maps. The update also includes hundreds of new OS signatures and new scripting engine modules.

The mapping facility is incorporated in the Zenmap GUI for nmap. It lays out the detected nodes in concentric circles based on how many hops away from the scanning system that node is. Details, screenshots and a guide to reading the maps have been added to the nmap documentation.

After Fyodor spent the summer scanning tens of millions of IP addresses, the results of his work have provided empirical data which has been used in Nmap 4.75 to improve the effectiveness of scanning.
