Recent old ages saw immense addition in Internet growing there were 40,073 webs on Internet ( as of 10/4/94 ) and it was duplicating about every 12 months. The current version ( IPv4 ) of Internet Protocol was sufficient for 20 old ages, but if Internet will go on to turn, reasonably shortly we will run out of references for all connexions because IPv4 can manage merely 32 spot references ( which are 1000000s of connexions ) . This is the major drawback of IPv4. The other issues is that IPv4 was non designed to manage existent clip applications such as picture and sound expeditiously and IPv4 can make a batch of atomization due to the deficiency of ability to foretell or observe the constrictions in the package & # 8217 ; s way.

The following coevals of IP was designed by Internet Engineering Task Force ( IETF ) to

manage all of these jobs and was foremost presented on July 25, 1994 in Toronto. Thousand

structurally it is really different from IPv4 ; it still incorporates all the successful characteristics of

IPv4 like its ability to accommodate to many topologies or engineerings at the same clip.

IPv6 is

increasing reference format from 32 spots to 128 spots. This addition gave

340,282,366,920,938,463,463,374,607,431,768,211,456 references ( should be more that

the package since exchanging the waies for each package will degrade public presentation of the

web. You ( good the protocol ) can bespeak the unbreakable way, for the applications

successfully transmit high quality picture and sound over the net. Another great advantage

of IPv6 is its compatibility with the IPv4. This will do passage between these two

versions painless. Because it doesn & # 8217 ; t count how good a new protocol is if there is no

practical manner to transition the current operational systems running IPv4 to the new protocol.

Structurally both versions are besides different. They have different datagram systems and unlike IPv4, IPv6 does non stipulate all the possible protocol characteristics, this makes it more adaptable to the user & # 8217 ; s demands. The datagram in

IPv6 consists of Base Header, Optional Extension Headers, and the Data Area. The Base Header is twice every bit big than in IPv4 due to the added excess 96 spots to the each finish and beginning references, but it really contains less informations. It contains: VERS – for version IPv6, PRIORITY – specifies the urgency

0 Uncharacterized traffic

1 & # 8220 ; Filler & # 8221 ; traffic ( e.g. , Netnews )

2 Unattended informations transportation ( e.g. , electronic mail )

3 ( Reserved )

4 Attended majority transportation ( e.g. , FTP, HTTP, NFS )

5 ( Reserved )

6 Synergistic traffic ( e.g. , telnet, X )

7 Internet control traffic ( e.g. , routing protocols, SNMP ) ,

FLOW LABEL & # 8211 ; designed for usage with public presentation dependent applications, PAYLOAD

LENGTH & # 8211 ; how much information is in the package, NEXT HEADER & # 8211 ; Tells what is the information

traveling to be in the following heading, HOP LIMIT & # 8211 ; same as clip to populate, and SOURCE and

DESTINATION references. The Base Header takes 40 eights without the optional

headings. The IPv6 besides differs in the manner it is delegating references. It has 3 different types:

unicast, multicast and anycast. UNICAST ( uni & # 8211 ; one ) reference corresponds to the individual

machine and datagram is given a shortest possible way. MULTICAST corresponds to the

set of nodes is dynamic they can alter over clip. ANYCAST sends one transcript of a

datagram to the group of Personal computers that portion same category prefix ( same web ) . IPv6 besides

saves infinite by utilizing & # 8216 ; 0 & # 8217 ; address compaction which works by compacting many 0 & # 8217 ; s in one row into smaller equivalent.

The other advantage of IPv6 over IPv4 is the better informations security. This is achieved by adding two optional extensions & # 8220 ; Authentication Header & # 8221 ; provide hallmark and unity to IPv6 datagrams. The 2nd security extension heading provided with IPng is the & # 8220 ; IPng Encapsulating Security Header & # 8221 ; this mechanism provides unity and confidentiality to IPv6 datagrams. Both extension headings are flexible and algorithm independent, this provides flexibleness and catholicity to them.
