IPv4 address is a 32-bit address and total number of addresses allowed by IPv4 is 2^32 which is equal to 4294967296. It was introduced in the year 1981 when the use of internet was very less and at that time 4 billion addresses was more than enough but in today's world internet users are growing at very fast rate and the IPv4 address is at the verge of exhaustion. So in near future the ISPs could not be able to assign ip address to the newly connected devices and there will be no internet for new users.
To overcome this problem IPv6 was formalized as the successor protocol and it 128-bit long hexadecimal address and number of address allowed by IPv6 is 2^128 which is equal to 3.4 × 10^38. IPv6 is not fully came into existence as there is some research is going on for IPv6, but in few years it will be default IP address.
