Why my network gears respond to my portscan for some non-existing IP addresses
Posted on 2011-09-15
When I use port scan software to scan some non-existing IP addresses, e.g. 10.22.22.22, 10.33.33.33 etc, in my company's network, I get following responses:
port 80 is open
port 25 is open
When I do the same scan at home I have different results: nothing is open.
My questions are:
1.) Why I have some ports opend on some non-existing IP address?
2.) Is it possible something is wrong with the code /software on Huawei network gears?
3.) Is there any other possiblity other than Huawei gear?
Any information and help would be much appreciated.
