Returned Address Sets always contains ip *.*.*.255

[gonzochic]

Hi, if you run Scan() the result will always contain the number of open ips on the specific port but always the same IP (e.g. 10.0.1.255 or 192.168.1.255).

This is caused because you dereference a variable inside a GO Routine which was referenced inside a Range Loop.

func (s *Scanner) Scan() []AddressSet {
	...
         // here you get a reference to the specific id
	for _, ip := range s.ips {

and then

                                                
                                                 // here you use the referenced IP which is at this time the last item of the range loop
						results = append(results, AddressSet{
							IP:       copyIP(ip),
							Port:     port,
							Protocol: proto,
						})
					

To fix that, you need to copy the id first into a variable and pass it into the go routine (as you did with address).

The current Scan() is unusable right now. I was thinking that something was wrong on my network. Thanks for the PR!

@jessfraz can you merge #7. Afterwards we can close.
