there is no class n ipv6

the ipv4 has classes for the efficient use on number of host n network bits.

in ipv4 there are only 4.3 billion of the 6.5 billion population so we need to care that it should be allocated efficiently

but n ipv6 there are 3.4 * 10 ^38 so each individual in the universe can have more than 1000 of address

so there is no need of classes

for more info u can refer....

www.cisco.com/ipv6 -> presentation of ipv6 addressing concepts.

hope u will enjoy reading this ..

ne more info feel free to mail me
