NScan is a very fast portscanner for Windows (up to 200 ports per second) for both hosts and large networks with numerous features: it scans not only address ranges, but also files with host lists (e.g. proxy list, domain zone or old log), writes logs at the different detail levels, has speed limits, pre-defined service sets and so on. It includes a set of additional tools: whois client, that supports automatic information recognition and fetch, has query history and other features; traceroute, that traces all the way to the host at once in one or two seconds, making route discovery tenth times faster; TCP-based DNS client that supports most of the available options, including AXFR zone transfer.
