Last night my box told me: "Backdoor Subseven blocked; 208.61.109.242

Am I right that someone tried to put this Trojon on my comp.?
Is the no. the ip address of the offending comp.?
Are ip addresses particular and specific to each comp.?
With the info I have can I learn anything else about the owner and/or the offending comp.?
Am I posting this properly?
