Internet protocol version for IP four is one of the core protocols of standards based networking methods
on the Internet.
It was described in IETF publication RFQ seven nine one in 1981, and it was the first version deployed
for production in the ARPANET in 1983.
It's still route's most Internet traffic today, despite the ongoing deployment of the successor protocol
IPV six.
With IPV for each address consists of four octets.
Arquette stands for eight digit binary numbers, so an IPV V4 address is 32 bits in total.
So that means we can theoretically address two to the power of 32 devices with IPV four.
So that means the address base of IPV four is about four point three billion.
Sounds like it's a big number, right?
IPV four is represented by the decimal equivalent of four octets separated by dots, the biggest number
one can make with eight binary digits is due to the power of eight minus one.
That means two hundred fifty five.
So each octet can be any number from zero to 255.
Now, also, there are special meanings associated with two different ending numbers in general, the
last number of zero stands for the network.
Let's call that the base address and a last number of 255 stands for all hosts on that network called
the broadcast address.
Computers that are on the same local network share three of the four nos.
A computer can be on more than one network, so it can also have several names.
