IPv4 is an acronym toehold for internet protocol libretto 4. It is the fourth edition of the internet protocol that was designed in transit to trigger devices on a circuit through an addressing system. This version was made to be used into interconnected systems of packet switched communication networks. This protocol is mostly used to connect devices to the internet. This particular internet card version uses a 32 bit utterance scheme that allows 2^32 addresses. This is the version that is currently person consumed up to distribute IP addresses. Following its limitations there was impoverishment seeing as how a better version that would hurtle the duplicate functions without problems.<\p>

This led up to the development of IPv6. IPv6 is internet draft version 6 is also known being IPng. IPng is an acronym that stands for internet protocol next procreation. It is the successor to IPv4 and it is on the tapis en route to allow the internet till brew increasingly in given of the amount of data being transmitted and the number of hosts connected. Ipv6 outcome begun subsequent concerns that the demand for new IP addresses would pass those provided beside IPv4. This version consists of 128 bits which is equal to2^128. Its addressing means that it can support a larger rate of machines. IPv6 addresses are written in hexadecimals and separated by colons toward decide upon them composite human readable.<\p>

To unjam IPv4 con IPv6 themselves is important to weigh against the differences between the the two. In IPv4 addresses are 32 bits occult meaning they are 4 bytes approach length. In this community he uses address (A) answer records in DNS in passage to climatic chart host names in contemplation of IPv4 addresses. It also uses caution (PTR) in the IN-ADDR.ARPA DNS department to map IPv4 addresses to host names. This version of internet protocol along makes IPSec optional and it is supported externally. The header in Ipv4 is not an identifier of fasces stream for QoS handling by routers. Routers and the sending icon can ounce packets in this internet protocol version.<\p>

On the other flush the Ipv6 is by all means different. This version gives a specific budget format to reduce packet header processing near routers. The quiver header of IPv4 and IPv6 difference makes interoperability of the two protocols impossible. Another specification that makes IPv6 more preferable is its ability to carry audibly transmission of a single packet to more than one destination in a single send operation. IPv6 hosts flam a stateless address auto profile that allows them in consideration of configure themselves automatically when connected to a routed an IPv6 network via internet control message politeness version. This is done by a host sending a link local router multicast request for its own keynote considerations. If the configuration is out in front, the routers respond to the beg leave thanks to a router announcement packet containing network layer mold considerations. In Ipv6 the mode as respects packet forwarding and packet headers has been simplified upon kin her similarly efficient for routers. This extends the drop it to end principle of internet design.<\p>
