Introduction to Computer Networks (ICN)

<ul><li>IPv6 is the next generation of IP protocol.&nbsp; </li><ul><li>Just like IPv4, It is used to assign the IP addresses to the machines for&nbsp;communication.</li></ul><li>IPv6 is born out of the concern with the eventual depletion of the IPv4 address space which was very limited </li><li>Traditional model of classful addressing of IPv4 does not allow the address space to be used to its maximum potential. </li><li>IPv6 uses a 128-bit address, theoretically allowing 2^128, or approximately 3.4×10^38 addresses. </li><li>The total addresses in IPv6 are&nbsp;</li><ul><ul><ul><li>340 undecillion addresses which translates to&nbsp;</li><li>340,282,366,920,938,463,463,374,607,431,768,211,456</li></ul></ul></ul></ul> <ul><li>Below we are comparing the IPv4 address header with IPv6 header which is clearly much larger than the IPv4. </li></ul>
