Well, if you know the full form, perhaps you can at least have a
framework in your mind about it’s definition.
The IP address, which is an acronym of internet protocol address, is
the unique identity of your computer over network.
Every machine on the internet or private network has a unique
identifying number, called an IP Address, which is essential for
computers to communicate with each others.
When you connect to the internet, either via your internet service
provider (bsnl, airtell,
etc.), or your office LAN connection, you are assigned an IP address.
This address identifies your computer from the other computers on the
internet. Your
IP address can be either static, meaning it never changes, or dynamic,
meaning each time you dial-in or login you are assigned a new address
for that session.
Check with your internet service provider or network administrator to
find out if your computer uses static or dynamic IP addressing.
A typical IP address looks like this:
192.168.1.1
we human express it in decimal for our convenience normally, but
actually computer communicates in binary form.
in the generalized words, IP address is like a mailing address,
without which communication can not be established between two
persons.
So, when two or more computers are connected with each others, whether
via internet or private network, they must require an unique address
to exchange data, informations, etc.
Of course, it assures that the informations which are exclusively for
a particular address must reach to it’s proper destination.
The four numbers in an IP address are called octets, because they each
have eight positions when viewed in binary form. If you add all the
positions together,
you get 32, which is why IP addresses are considered 32-bit numbers.
Since each of the eight positions can have two different states (1 or
0) the total
number of possible combinations per octet is 28 or 256. So each octet
can contain any value between 0 and 255. Combine the four octets and
you get 232
or a possible 4,294,967,296 unique values!
I said, that it’s the address for communication between computers
over network, but what if the computer is not connected to any
network?
And, I think that’s what your question is.
Out of these 294,967,296 unique values, certain values are restricted
from use as typical IP addresses.
Now, this is what the answer of your question. Even If you are not
connected to any network, still you would have a default IP address,
which is 0.0.0.0.
So, this is something reserved, yet unique itself.
How to check IP address:
Go to command prompt by start/run/cmd, and type the following command as it
is:
Ipconfig
This will present your IP address along with other informations like
default server, dhcp server, subnet mask, etc.
Though there some other ways as well to access the IP address, but
this is my personal favorite, and in fact it’s the most easiest and
genuine method for checking the IP address.
Hope it helps.

Subject: [AI] How can we know the IP address of our computer?
Dear Members,
A staff member of mine asked me how we can know the IP address of our
computer. And also, can we get the IP address of our computer even if
our computer
is never connected to the internet? In other words, is there any
connection between the IP address and the internet?
Please throw some light on this topic.
Thanking in anticipation.
