NetScanTools is a collection of common and specialized Internet utilities. Many functions, such as Ping, Traceroute, and NSLookup, are very familiar to network professionals. All the functions are grouped in a tabbed dialog interface. The program features zone-transfer domain listings; Ping, Traceroute, and Whois queries with automatic server selection; a port scanner; a network Ping sweep scanner (NetScanner); time syncing; NetBIOS information and local shares; service and protocol database checks; and a simple URL grabber.

You can translate an IP address to a hostname or vice versa. Use NSLookup from a graphical interface, access any server for DNS records, find the authoritative DNS for a domain, list all the computers registered in a domain, probe ports on target computers for TCP services, sweep an IP address range looking for active computers, diagnose network connectivity problems, plot Ping and Traceroute time-response graphs (and print them), check to see if a domain name has been used with the Whois utility, find the responsible business or person for a domain, synchronize your computer clock with network time servers, use TCP terms to test services on both standard and non-standard TCP ports, view hidden headers on Web pages, view NetBIOS shares on your local network, and gather MAC addresses of those shared computers.
