There is no PTR record in the DNS for this IP address? Help!?

the internet is an untrusted domain. there is a lot you can do that is cunning and naive. you can have devices that generate IP Adresses that look like it originated from another country while in fact it could have been your neighbour. hackers and attackers normally try to use various means, such as a proxy in another country, ip generators, or even use another computer in another country to launch an attack on someone else. the methods and means go on and is very vast. so yes your umption is correct too
