Ip address help

So can somebody explain the concept of an IpAddress to me? I was trying to start up an online game and it was giving me trouble, so I looked into it, and apparently mine.... fails. I dont have any problems with the internet, usually, so...

Your IP address is your computer's identifier. When other computers look for you, they look for a number. Meanwhile, you name your computer, but it is much easier for a computer to keep a number, as numbers are more consistent.

As such, each computer must have an IP when being on a network. Now, there is your local network, and your online network. For your local network, you can choose any number you want. Most opt for 192.168.0.1-25, though you can choose anything like that. Computers on the network will share the first 3 lots of numbers, the fourth being different. This allows the computers on the network to recognise you.

Then you have your online IP address. This is given to you by your ISP. When you connect through the modem, it will assign you this unique IP address, so other computers and websites etc. can recognise you.

Now, to play things on the net, one computer finds the other computer through the IP address. To find your online IP address, an easy way is to go to http://www.whatismyip.com. They will tell you what your IP is.

To find your offline IP address, simply open up DOS prompt, and write in ipconfig.

Hope you understand this and I'll answer any future questions.

some ISPs have a range of IP addresses they use so sometimes you will get a different one everytime you connect to the internet (thats how it is with my connection). The easiest way I find to check for your IP address is to double click on the internet icon on the quick menu on your desktop and then just select details. If I do that on my pc it tells me my IP address for this internet session.

Some IP problems may occur when using certain routers... Or maybe even firewalls denying direct connection which is then mistaken for an IP-error.

Just trying to scare you a little

Here are some more details about my problem. I bought FFXI the other day, and i needed to update my version online before i could play. So when the program tries to connect to some server it pops up a box saying that either the server was busy or that my connection isn't working. It lists my IP Addres, and my global IP, so i looked into it. while searching through my computer i found a list of my connection info. Next to my IP address it said invalid, or fail next to it. I'll look at that site... Keep it coming brothers

Okay, first of all, I would say you are running a firewall. This will stop outgoing and incoming connections unless you specifically allow it, normally a pop-up button will occur, but you can't be certain. Now if you don't think you are running a firewall, or the firewall has allowed it, it could be another thing...

Windows XP Service Pack 2. Because Windows is about as bullet proof as a teddy bear, they decided to add in a weak, virtually useless firewall. All it does is annoy and stuff up things. Now, go to 'Windows Security Centre' and check the firewall. If it is on, turn it off. You might think it is dangerous, but anyone with remote hacking ability can defeat it, so it's doing barely anything. Instead, get a real firewall if you don't have one.

Try that, and let me know how it goes.
