What Is IP Address ?
What Is IP Address ?
hey guys this is DG today we are going
to understand what is an IP address and
how you can find your computers or a
smart phones IP address so let's start
computers in Internet communicate with
each other with underground or
underwater cables or wirelessly if I
want to download a file from Internet
then my computer should have an address
so that other computers in Internet can
find and locate my computer in internet
terms that address of computer is called
IP address let us understand it with
other example like if someone wants to
send you a mail then he or she should
have your home address
similarly your computer also needs an
address so that computers in Internet
can send you a file that you want to
download that address in internal terms
is called IP address which is nothing
but a string of numbers written in a
certain format note this comparison this
is your home address which is identified
by your area postman and you get all the
things delivered in this address
similarly this is your computer address
which is identified by the computers in
Internet and you get all the downloads
available at this computer address this
address is the IP address of your
computer IP address stands for Internet
Protocol address but what does this mean
internal protocol is a set of rules that
makes Internet work you are able to
watch this video this time in YouTube
only because your computer or your
smartphone has an IP address and YouTube
is sending you all the data related to
this video to this IP address IP address
is of two types Internet Protocol
version 4 and Internet Protocol version
6 Internet Protocol version 4 consists
of 4 numbers separated with the dot each
number can range from 0 to 255 in
decimal numbers but computers do not
understand these decimal numbers so
these numbers are converted to binary
form which is computer understandable
therefore in binary this range can be
written as 0 0 0 0 0 0 0 0 2 1 1 1 1 1 1
1 1 since each number n is represented
by a group of 8 binary digits
so the
whole ipv4 address is represented by a
sequence of 32 ones and zeros or simply
I should say by a sequence of 32 bits so
ipv4 is a 32-bit address in ipv4 a
unique sequence of ones and zeros is
assigned to each computer therefore a
total of 2 raised to power 32 devices
that is approximately 4 billion devices
can be addressed and connected to
internet with ipv4 but there is a
problem with this 32-bit ipv4 address
with ipv4 we can connect only this
amount of devices to Internet but these
days we have devices like computers
smart phones far more than 4 billion so
slowly we are moving towards ipv6
address which is a 128-bit IP address in
human friendly form ipv6 is written as a
group of 8 hexadecimal numbers separated
with colons for example in human
friendly form the ipv6 address can be
written like this while in computer
friendly form ipv6 address can be
written by a sequence of 128 ones or
zeros since a unique sequence of ones
and zeros is given to each computer
connected to internet so with ipv6 a
total of 2 raised to power 128 devices
can be connected to internet that is
ipv6 can address this amount of devices
which is actually far more than enough
for many future generations
to find your computer's public IP
address right what is my IP in
www.google.com Google will tell you your
computer's public IP address similarly
to find your smartphone's public IP
address right or just say what is my IP
in your smartphone Google will tell you
your smartphone's public IP address
without this numeric protocol we would
not be able to connect to internet and
without internet we would be standing in
long queues to get our train tickets we
would be looking at newspapers to see
where jobs are available and we would be
buying storage devices like CDs because
without Internet cloud storage would not
work so IP address is must for internet
connection
IP address can be classified as dynamic
IP address and static IP addresses
starting with dynamic IP addresses when
you connect your device like smartphone
or computer to Internet Internet service
provider provides you an IP address from
the range of available IP addresses now
your device has an IP address so you can
connect your device to Internet and send
and receive data to and from the
computers in Internet next time you
connect your device to Internet your
internet service provider provides you
some different IP address but from the
same available range since IP address
keeps on changing every time you connect
your device to Internet so such IP
addresses are called dynamic IP
addresses now static IP addresses static
IP addresses never change they serve as
permanent Internet address static IP
addresses are used by DNS servers what a
DNS servers actually these are computers
that help you to open a website in your
computer static IP addresses provides
information such as device is located in
which continent which country which city
and which Internet service provider
provides internet connection to that
device once we know
who is the intent service provider we
can trace the location of the device
connected to internet therefore IP
address allows billions of digital
devices to be pinpointed static IP
addresses are considered somewhat less
secure than dynamic IP addresses because
they are easier to track
however following safe internet
practices can help you to keep your
computer secure no matter what type of
IP address you use if this video was
