IP is the internet protocol that uniquely identifies a system on a network and there are 2^128 addresses in IPv6 (IP version 6).
256*256*256*256
IPv4 addresses are 4 bytes. IPv6 IP addresses are 16 bytes.

IP addresses are of two types IPV4 and IPV6 . Depending upon the version the length of IP address differs . IPV4 is 32 bit long and IPV6 is 128 bits long.
It is literally impossible to calculate how many IP addresses there are around the world. The number people connecting online and offline are always changing so the number IP addresses are always changing.
Dotted-decimal notation
IPv4 addresses have 4 octets, each octet separated by a period. For example, at this time, one of Yahoo's servers has an ip address of 67.195.160.76.
a TcP IPv4 ip address has 32 bits.
IPv4 is 32 bits wide, or about 4 billion IP addresses; while IPv6 is 128 bits wide, or about 3.4x10^38 IP addresses. The number of addresses between the two has a difference of 79x10^27 times bigger. It is calculated that the world's energy output combined could only support using 1/3rd of the available addresses in this address space.
Because there are only a certain number of IPv4 IP addresses, We will eventually run out
IP address are the unique address. IP or internet protocol addresses are also known as logical addresses . The 32 bit address is the IPV4 address.
IP addresses are divided into five IP classes:IP address class AIP address class BIP address class CIP address class DIP address class E
In theory there are 264 available network allocations in ipV6. It is not known how many are actually in use at this time. For a very clear comparison, in IPv4 there is a total of 4,294,967,296 IP addresses. With IPv6, there is a total of 18,446,744,073,709,551,616 IP addresses in a single /64 allocation.
