I worked with a guy who went onsite to install a router with information he was given from the local Internet Service Provider (ISP). When he arrived onsite and he attempted to install the router, he was unable to connect to the Internet. He and I went back and forth about the possible issues and after a few minutes, I asked him to text me the information he was given by the ISP. When I looked at the message, it became immediately clear as to what was causing the problem.
Not using the actual IP information, this will suffice:
IP Address: 255.255.255.0
Subnet: 192.168.168.10
Gateway: 192.168.168.1
You could look at this information and the problem might be completely obvious to you – or perhaps not. The point being that to call this post a primer on pentesting would be to ignore the entire foundation where the majority of this work exists – the network.
