Active and Passive Discovery Tools
Actively sends ARP packets to every IPv4 address within
range of IPs on your LAN. Shows all active devices,
firewalled or not.
Passively listens for incoming connections to your computer's
TCP/UDP ports. Logs connection attempts.
DHCP Server Discovery
Actively looks for DHCPv4 servers on each network attached
to your computer.
Duplicate IP Scanner
Scan your subnet for duplicate IPv4 addresses being
shared by two or more devices. Limited to the current subnet.
Actively uses Multicast Ping to identify nearby IPv6 devices.
Network Shares - SMB
Actively uses SMB/CIFS/NetBIOS protocols to find computers
in a workgroup. (formerly called NetBIOS Info - Basic). Deprecated in favor of the SMB Scanner
Network Routing Visualizer
Actively uses traceroute to find the routes taken by
packets to a list of targets. Shows the results in a
tree format. (formerly called Net Topography)
Passively listens to network traffic on a selected interface
and records it in a file for review.
Passively listens to network traffic on your LAN and
shows which computers are talking.
Ping - Enhanced
Actively uses ICMP, TCP, or UDP to find active devices.
Supports both IPv4 and IPv6. Shows min/max/avg latency, jitter and a timing chart.
(also called NetScanner)
Actively scans a range of IPv4 addresses looking for
responses. The range can be on your LAN or across the
internet. Shows timing chart.
Actively scans a computer or other device for open TCP
or UDP ports.
Actively scans your subnet or LAN for computers or devices
with the network interfaces set in Promiscuous Mode.
It indicates devices possibly capturing packets.
Actively communicates with *nix Portmapper service.
Retrieves SMB versions supported by a target.
Actively scans a range of IP addresses for devices with
active SNMP v1 or v2c.
System Info - SMB
Actively uses SMB/CIFS/NetBIOS to communicate with a
device and show a number of parameters. (formerly called
NetBIOS Info - Advanced)
Actively uses ICMP, TCP, or UDP to find the route taken
by packets to a device. Supports both IPv4 and IPv6.
Shows timing chart.
Traceroute - Graphical
Actively uses ICMP to constantly find the route taken
by packets to a device and gather statistics about
packet loss and timing. The cumulative timing is
shown in a real time chart. Supports both IPv4 and IPv6.
