yesterday wen i was jus pinging localhost..
instead of writing 127.0.0.1 i wrote 127.9.0.3
soo C:\>ping 127.9.0.3
Why did you type in the 'wrong' IP ?
What were you thinking of at that time ?

I'm in agreement on loopback, just curious as to why you typed it out wrong in the first place. Could it be something you were working on ?
