IPv6 stands for the 6th iteration of the Internet protocol. Before moving to the functionalities of IP Version 6, let us know a little bit about the Internet Protocol in Whole.
Internet Protocol accommodates transmitting pieces of data information called datagrams. These datagrams are transmitted from the sources to the destinations. The identification of these sources and destinations is done by the hosts of consistent addresses.
The Internet Protocol additionally accommodates discontinuity and reassembly of lengthy datagrams for transmitting them through smaller data packets; if necessary at all.
The internet protocol executes two essential capacities: Fragmentation of data packets and addressing of data packets. The web modules utilize the locations conveyed in the web header to transmit web datagrams toward their destinations. The determination of a way for transmission is called routing.
The web modules use fields in the header to part and reassemble web datagrams when vital for transmission through “little parcel” systems. The mode of operation of IP is that a web module dwells in every host occupied with web correspondence and in every passage that interconnects the systems. These modules offer normal principles for deciphering address fields and for dividing and amassing web datagrams. These modules have strategies for settling on steering choices and other capacities.
IP version 6 (IPv6) is the latest rendition of the Internet Protocol – which is composed as the successor to IP version 4 (IPv4). IPv6 adoption is quite interesting thing that has taken place in recent past.
The changes from IPv4 to IPv6 fall basically into the accompanying classes:
Extended Addressing Capabilities: IPv6 expands the traditional IP address size from 32 bits to 128 bits. It includes a much more prominent number of addressable hubs, and less complex auto-arrangements of addresses. The versatility of multicast directing is enhanced by including a “degree” field to multicast addresses. Also, another short of location called “anycast location” is characterized which is used to send a bundle of any of a gathering of hubs.
Header Simplification: There are many of IPv4 header fields which have been dismantled or made discretionary. This was done to lessen the regular case preparing expense of parcel handling and to restrain the transfer speed expense of IPv6 header.
Enhanced Support for Extensions: Above mentioned changes in IPv4 header files allows IPv6 enhanced headers to be more productive in sending, less stringent points of confinement on the length of options, and more noteworthy adaptability for presenting new choices later on.
What is the similarity between the routing header of IPv4 and IPv6?
The routing header in IPv6 origin is used to note the middle hosts which are supposed to be visited while transmissions to the final destination. This functionality is quite close to the IPv4 record and loose source options.
What is “Next Header” in IPv6?
Next header in IPv6 can be defined as an 8-bit selector which automatically gets the admin information of the primary header which follows the main routing header. Interestingly, the “Next Header” of IPv6 uses the traditional IPv4 field values.
It is quite apparent that IPv6 is here to stay. More of technical details will be unveiled in the upcoming blog posts. Keep reading and getting informed.
