It is the most recent version of the protocol for the Internet. It was started in early 1994 by the Internet Engineer Taskforce. The suite's design and development is now called IPv6.
To satisfy the need for more Internet addresses, this new IP address version is being deployed. It was intended to fix problems associated with IPv4. With 128-bit address space, it makes specific address space for 340 undecillons. IPv6 is also called IPng (next generation of Internet Protocol).
To build a single unique address on the network, IPv6 utilises 128 binary bits. Eight groups of hexadecimals (base-16) numbers, separated by colons, express the IPv6 address, as in 2001: cdba:0000:0000:0000:0000:3257:9652. In order to save space, groups of numbers containing all zeros are sometimes omitted, leaving a colon separator to denote the gap (as in 2001: cdba::3257:9652).
Compared to IPv4, Internet Protocol version 6 (IPv6) is more advanced and has better functionality. It has the capacity to supply an unlimited number of emails. To satisfy the increasing number of networks across the world, it replaces IPv4 and helps solve the issue of IP address exhaustion.
One of the discrepancies is the presence of the IP addresses between IPv4 and IPv6. IPv4 uses four decimal numbers of 1 character, separated by a dot (i.e. 192.168.1.1), while IPv6 uses colon-separated hexadecimal numbers (i.e. fe80: d4a8:6435: d2d8: d9f3b11).
