Features:

• network scanning for active hosts;
• scanning by a specified range of IP addresses;
• support for UDP and TCP requests;
• for each found computer, you can determine the computer name on the network, its workgroup and the MAC address of the network card;
• viewing open ports on computers in the local network;
• quick access to telnet, ssh, ftp, web server, etc.

ZenMap (NMap) is a deep network or host scanner for determining the state of scanned objects (ports and corresponding services).
The following methods are used for scanning: UDP, TCP (connect), TCP SYN (half-open), FTP-proxy (breakthrough via ftp), Reverse-ident, ICMP (ping), FIN, ACK, Xmas tree, SYN and NULL scanning, etc.
Additional features: OS detection, "invisible" scanning, dynamic delay calculation and packet retransmission, parallel scanning, detection of inactive hosts, scanning using false hosts, detection of the presence of packet filters, direct RPC scanning, scanning using IP fragmentation, etc.
