TCP Sweep

TCP Sweep is a network utility that quickly scans a list of TCP ports (up to five ports) over a universal IPv4 range (up to 1500 hosts).

You have to specify a start IPv4, an end IPv4, ports and port ranges as arguments (that are separated by comma), and connection timeout.

Results can be copied to clipboard by one button click.

All results are grepable.

Enjoy!

P.S. I can significantly increase maximum host limit at request! (I am a bit too lazy to do that right now...)

P.P.S. I can also increase maximum port limit per host.
