Someone launched a dictionary attack against my machine.
Nothing new...

However, I always use IP2Location to see where 
the attack is coming from.. just for my curiosity.

This particular IP, 167.206.75.27, was from New York so I figure I would 
try to find the ISP to complain.

dig -x reports

;; ANSWER SECTION:
27.75.206.167.in-addr.arpa. 78337 IN    PTR     ros75-27.optonline.net.

but then
dig ros75-27.optonline.net
;; QUESTION SECTION:
;ros75-27.optonline.net.                IN      A

Tried traceroute and mtr, but got nowhere.
Not even ping did anything when I tried
ping 167.206.75.27


Is it possibly the attacker just spoofed the IP?
