Dear Sir or Madam
I have some customers who I have allocated high band width with wide ranges of IPv4 addresses to. Because of lack of IPv4, I would like to see that how many IPs they are using. It would be grateful if you tell me how can I do this and what soft ware I have to use to monitor the used IPs.
I would like to thank you in advance and I am looking forward to hearing from you soon.
Hi, what you might want to do is a ping sweep. However it is effective only against hosts that allow ICMP echos. For those customers that block ICMP I think your only option is a port scan, which might not be desirable. For both ways your best choice is nmap [1]. BR, leonardo [1] http://nmap.org/
