Hey guys I was just curious as to what other ip there is on your computer?
Isn't there just an ip address? I remember hearing about it somewhere, don't know if its true.

If so, what does it do? and where does it come from?
 
There is an IP address for each NIC (network interface card). I believe you also receive an IP by connecting a USB modem, but I'm not sure on that.

There are basically two different types of IP addresses, internal and external. The internal IP (usually 192.168.x.x) identifies your computer/NIC on your local network, and only people inside that network can find out information from that IP. Your external IP is usually assigned to the cable/DSL modem, and can be accessed anywhere in the world over the internet.
 
So basically do you get internal and external ip's from your cable?

Or does internal ip come from a computer?
I.E if i buy a new computer, does it come with a new internal ip?

Thanks for the input, I was always curious.

The internal IP will be assigned automatically (unless you've set the IP manually, of course) when the computer connects to a network/router.
 
Ah so time warner basically sets an internal ip which I will have forever even if I change a new comp or a new modem correct?

And just out of curiosity, why is it needed?
As I am assuming external ip is necessary to go online.

No. Time Warner or any ISP for that matter has absolutely NO control over your internal IP(s). The operating system will automatically assign you an IP, period. It's all to do with how your network has been set up.

IP address? What do you need street addresses for? Imagine this, suddenly, all street names simply disappear, as well as house numbers, state and country names. No location, country, municipality, or street would have a name or any kind of ID for that matter. And then someone asks you to run the post office... gives a pretty good idea of why IP addresses are needed.

Yes. External IP is the one through which your network/router is identified... not having an external IP is like living in a house without a number in a nameless street. You'll never get your mail; the system ain't gonna work.
 
oh ok lol. So your os is the 1 with a internal ip. Thus if i reinstall windows or vista it'll create a new internal ip.

So I will have the same internal ip as long as I never change my os on my computer?

Interesting info, thanks bro

Well, not really the OS... every NIC in the system gets its own IP, which is internal. However, the OS assigns these IPs.

Not sure about that, but I'd think so...my lappy always gets the same IP when I connect to our wireless adhoc (I'll have to check out what happens when I connect to a different network).
