I am new to the field of penetration testing, and I'm currently testing an application, for learning purposes with their legit, written permit. When I did a
nslookup for that site, it returned me an IP address. But accessing the web directly through that IP address, displayed a server default page which said, the page has been removed or site has moved. However, the site can be accessed via the domain name.
My question is, whether the port scan results generated by nmap returns the correct ports for that website? Or is that result, applied for all the websites hosted on that shared server? please correct me, if I'm wrong at any point.
