Yes ofcourse there are so many port scanners in which u can change ur ip address i.e. you can use proxies. Infact a good port scanner must have a capability ot change ip address as normally if u scan a server for more than 5-10 ports, the server will ban your ip address and even if the other ports are open . . it will act like all the ports are closed.

one of the best out there is AD

It is a very good software ot detect any security failure on your website or webserver or even your PC. All you need is to download it . .. as it is a very user friendly software.

And in the end i must say, its the thing which is bad but it is the way you use it which makez it bad, as many of hackers out there are using it for other purposes. I hope you will use it for good pupose.


Take Care and
Best Of Luck
