Diff Between IPV4 and IPV6 ?

PV4 is 32 Bits and IPv6 is a 128 bits long IP address
The terms bit and byte are common in computer networking. Both terms refer to digital data transmitted over a network connection. For example, bits and bytes both may represent network addresses
What is IPv4?
IPv4 was the first version of Internet Protocol to be widely used, and accounts
for most of today’s Internet traffic. There are just over 4 billion IPv4 addresses.
While that is a lot of IP addresses, it is not enough to last forever.
What is IPv6?
IPv6 is a newer numbering system that provides a much larger address pool
than IPv4. It was deployed in 1999 and should meet the world’s IP addressing
needs well into the future.

What is the major difference?
The major difference between IPv4 and IPv6 is the number of IP addresses.
There are 4,294,967,296 IPv4 addresses. In contrast, there are 340,282,366,920,938,463,463,374,607,431,768,211,456 IPv6 addresses.The technical functioning of the Internet remains the same with both versions
and it is likely that both versions will continue to operate simultaneously on
networks well into the future. To date, most networks that use IPv6 support

both IPv4 and IPv6 addresses in their networks.
