is ip-adress unique to a computer or an internet connection or none, how to find my unique(if at all it is) ip

Answer 1

Every time you sign into your ISP the server assigns your computer an IP number. That number will change every time you sign in. Its a random assignment of available numbers at any given time. There is a way to find your IP number for a given login event, but it would differ from ISP to ISP.... depends on who you are with.

Answer 2

If you are using a Dial-Up connection, you will always be given a new unique IP address. If you want to check your IP do the following -
1. Go to Start and click Run
2. Type CMD and press OK
3. Type 'ipconfig' in the DOS window. Don't forget to press enter :-)
4. Now, you will get something like
----------------------------------
Windows IP Configuration


Ethernet adapter Local Area Connection:

Connection-specific DNS Suffix . :
IP Address. . . . . . . . . . . . : 192.132.19.35
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.131.17.45
----------------------------------
The line that shows IP Address is your CURRENT IP!
Now, try yo disconnect and then, again connect. Now, follow the same procedure. You will be assigned a new IP. That's how the mechanism works under IPv6.0

But the scenario is very different if you are using a Broadband service provider - You will be ginven a static IP and that will remain constant throughout lifetime of that connection. Meaning, you are more prone to attackers... all they should know is your IP that's it. If your system has loopholes, you are smacked... for no reason of yours. To prevent yourself from such attacks, use tools that are avalable free online that will "Mask" your original IP and instead, will assign a fake IP so that hackers or spammers can't bug you! One of the classic tool is "Hide IP Platinum" you can download and install and each time, it will mask your original IP. Thus ensuring proper security. Also, use some Firewall such as Norton Internet Firewall 2007 which has good inbuilt tools to secure your PC and important information.

The answer is - it depends on what you mean. Your ip address identifies you within your network. If you connect to the internet via a DSL or cable modem, then what happens is that your modem is assigned an ip address that is unique to it by your internet service provider (ISP). That ip address is the ip address that all computers hooked into your modem will connect to the internet through. You can find this address in your modem's configuration software (check your users manual) or go to http://ip.nefsc.noaa.gov/ .

Now, so your modem can send the right information to any computer hooked into it, it also acts as a router (also called a DHCP server) for its own network and assigns each computer an internal ip address on that network, even if there's only one computer hooked up to the modem. That ip address isn't shared with the internet, and is usually something like 192.168.1.2 or something, because your modem or router comes with those numbers set up as default. You can find that ip address by going to Network Connections in your Control Panel, select your LAN connection and click the Support tab.

That's the basic setup. It gets a lot more complicated, trust me!

Answer 4

To a internet connecting to a network each computer(router) has a Unique IP address, but if a system wants to two or more network then it needs two or more IP address, A simple example of this is a router with two interface S0, S1 serial interface each of them has a separate IP for each interface, Same appplies if we talk for a computer,



Depends if you are using DHCP or Static address, In case of DHCP it changes from time to time, A ISP has a IP pool of addresses, and it allocates a IP address which is Unique however for the leased time.


Static IP doesnot change with time to time,


To see your IP address and MAC address
DOS command.
IPconfig /all
