OK I have a quick question about, Net security. I met a really “cool” guy on the net. And he told me one time that he can get my IP number (whatever that is) that easily. Here’s my questions, is it possible that he can do it, or he was just saying that to scare the crap out of me? And one more question. What EXACTLY is an “IP number”? This may sound awefully dumb. But I’m not that “smart” when it comes to computer “stuff” related. And, is there any way where I can avoid people who I met online see my IP number or any other documents from my computer? Thanks 🙂

Every computer connected to the Internet uses an IP number to identify itself to the rest of the net. This includes web servers. You can check this very easily by opening a command window and typing ping http://www.yahoo.com. You’ll see an IP address returned such as 66.218.71.83. Knowing an IP address doesn’t mean they know where you live, or even who you are. It just means they know what IP address your computer is using at the moment.
Your programs need IP addresses in order for computers to connect together (for direct chat, voice, webcam, many games, etc.). Most of the time this is all handled behind-the-scenes and you don’t even realize it’s going on. But yes, it’s pretty easy to peek behind the curtain and see the IP addresses involved.
Is this a danger? Usually not. Think of the analogy of giving your real address (where you live) to a new person you meet. Just because they know your address, this doesn’t mean they can unlock the front door, walk right in and take whatever they want. For that, they need your permission (you open the door) or a key (something you probably don’t give to someone unless you really trust them). Of course, you could get sloppy and leave the door unlocked, or worse yet, swinging wide open!
Your IP address is much the same. Knowing it is not enough to cause harm to your computer. But you need to be cautious to keep the door locked. 😉
This topic was discussed previously (and extensively) in this topic. You’ll find a lot of additional information about IP addresses, the risks they present, and what you can do to protect yourself from the bad guys.
