IPV4 uses a 4 byte address, whereas the IPV6 uses a 16 byte address.
IPv4 has a possible 4,294,967,296 IP addreses. The IPv6 has over 300,000,000,000,000,000,000,000,000,000,000,000,000 possible address's.

IP addresses are divided into five IP classes:IP address class AIP address class BIP address class CIP address class DIP address class E
One major block of addresses reserved for special purposes is the IPv4 experimental address range 240.0.0.0 to 255.255.255.254. Currently, they cannot be used in IPv4 networks. However, these addresses could be used for research or experimentation.
IPv6 is based on IPv4, it is an evolution of IPv4. So many things that we find with IPv6 are familiar to us. The main differences are:1.Simplified header format. IPv6 has a fixed length header, which does not include most of the options an IPv4 header can include. Even though the IPv6 header contains two 128 bit addresses (source and destination IP address) the whole header has a fixed length of 40 bytes only. This allows for faster processing.Options are dealt with in extension headers, which are only inserted after the IPv6 header if needed. So for instance if a packet needs to be fragmented, the fragmentation header is inserted after the IPv6 header. The basic set of extension headers is defined in RFC 2460.2.Address extended to 128 bits. This allows for hierarchical structure of the address space and provides enough addresses for almost every 'grain of sand' on the earth. Important for security and new services/devices that will need multiple IP addresses and/or permanent connectivity.3.A lot of the new IPv6 functionality is built into ICMPv6 such as Neighbor Discovery, Autoconfiguration, Multicast Listener Discovery, Path MTU Discovery.4.Enhanced Security and QoS Features.Answer:IPv4 means Internet Protocol version 4, whereas IPv6 means Internet Protocol version 6.IPv4 is 32 bits IP address that we use commonly, it can be 192.168.8.1, 10.3.4.5 or other 32 bits IP addresses. IPv4 can support up to 232 addresses, however the 32 bits IPv4 addresses are finishing to be used in near future, so IPv6 is developed as a replacement.IPv6 is 128 bits, can support up to 2128 addresses to fulfill future needs with better security and network related features. Here are some examples of IPv6 address:1050:0:0:0:5:600:300c:326bff06::c30:0:0:0:0:0:192.1.56.10The most important difference is that it has a larger address space. IPv6 uses 128 bits, instead of the 32 bits used in an IPv4 address.There are also some changes in the header format, and some additional options, like built-in security options. These can be added to IPv4 through additional protocols, so this is really no big deal.IPv4 is like 10.36.05.2 while IPv6 is one huge garble.IPv4 is a 32 bits IP address that we use commonly, it can be 192.168.8.1, 10.3.4.5 or other 32 bits IP addresses.

IPv4 uses 4 bytes; IPv6 uses 16 bytes for the address.Mainly, IPv6 has a larger addressing space; IPv6 addresses use 128 bits instead of 32 bits.

IP version 6, also known as IPv6, IP next generation, or IPng. It uses addresses of 16 bytes, instead of the 4 bytes used in IPv4.

Number 0 is used at the end of an IPv4 address for network identifiers and number 255 is used at end of an IPv4 for broadcast addresses.
The IPv4 address is identical for all hosts in a broadcast domain. The IPv4 addresse varies in length. The IPv4 address is used to forward packets.
An IPv4 address of 75.76.77.68 is considered a Class A address. A class A address ranges from 1.0.0.0 to 126.0.0.0
IP address is a logical address of a system which could be used to identify it. There are 2 types of IP address, IPV6 and IPV4.
128 Bits. An IPv6 address is made up of 8 fields consisting of 16 bits per field. If you multiply 8 x 16 will get 128 bits. Each field is separated by colons unlike IPv4 which was separated by dotted decimal notation. A good link to go to to see the address and how sub-netting is done is on the related links below.

IP version 6, also known as IPv6, IP next generation, or IPng. It uses addresses of 16 bytes, instead of the 4 bytes used in IPv4.
It is IPv4 (Internet Protocol Address version 4) used to identify the user on the Internet.
To address the exhaustion of available IPv4 addresses, Network Address Translation (NAT) is commonly used. NAT allows multiple devices on a private network to share a single public IP address, enabling continued internet connectivity while conserving the limited pool of IPv4 addresses. This method effectively extends the usability of IPv4 by allowing organizations to use private IP addresses internally and translating them to a public address for external communication.
