What is IPv6? What are the benefits of IPv6 Addressing? Write the historical development of IPng.
Internet Protocol version 6 (IPv6) is the latest revision of the Internet Protocol (IP), days
of IPv6 protocol development stage the communications protocol that routes traffic across
the Internet. IP stands for Internet Protocol which is one of the main pillars that supports the

called IPng in the early. It is intended to replace IPv4. IPv6 was developed by the Internet
Engineering Task Force (IETF) to deal with the long-anticipated problem of IPv4 address
exhaustion.
Every device on the Internet, such as a computer or mobile telephone, must be assigned
an IP address for identification and location addressing in order to communicate with other
devices. With the ever-increasing number of new devices being connected to the Internet,
the need arose for more addresses than IPv4 is able to accommodate. IPv6 uses a 128-
bit address, allowing 2128, or approximately 3.4×1038 addresses, or more than 7.9×1028 times
as many as IPv4, which uses 32-bit addresses. IPv4 allows only approximately 4.3 billion
addresses. IPv6 provides enough addresses to allow the Internet to continue to expand and the
industry to innovate. It is not, however, directly compatible with IPv4, meaning that a device
connected via IPv4 cannot communicate directly with a device connected using IPv6. IPv6

During the late 1980s (88-89) Internet has started to grow exponentially. The ability to scale
Internet for future demands requires a limitless supply of IP addresses and improved mobility. In

to develop a new protocol for Internet. In 1994 IETF gave a clear direction of IPng or IPv6 after
a long process of discussion.
Benefits of IPv6:
More Efficient Routing: IPv6 reduces the size of routing tables and makes routing more
efficient and hierarchical. IPv6 allows ISPs to aggregate the prefixes of their customers'
networks
More Efficient Packet Processing: IPv6's simplified packet header makes packet processing
more efficient. Compared with IPv4, IPv6 contains no IP-level checksum, so the checksum does
not
because most link-layer technologies already contain checksum and error-control capabilities.
Directed Data Flows: IPv6 supports multicast rather than broadcast. Multicast allows
bandwidth-intensive packet flows (like multimedia streams) to be sent to multiple destinations
simultaneously, saving network bandwidth. Disinterested hosts no longer must process broadcast
packets.
Simplified Network Configuration: Address auto-configuration (address assignment) is built
in to IPv6. A router will send the prefix of the local link in its router advertisements. A host can
generate
Universal Identifier (EUI) 64-bit format, to the 64 bits of the local link prefix.
Security: IPSec, which provides confidentiality, authentication and data integrity, is baked into
in IPv6. Because of their potential to carry malware, IPv4 ICMP packets are often blocked by
corporate firewalls, but ICMPv6, the implementation of the Internet Control Message Protocol
