Understanding IPv6
IPv6 uses 128 bits as opposed to 32 bits of an IPv4 address and this results in a new address space of 2pow128 that is, over 4 billion of available addresses. IPv6 allows for multiple levels of subnetting. The enormous address space created by the 128 bit format give us the option of allocating more than one IPv6 address to a host, with each address serving a specific purpose. In IPv6 we find addresses that are equivalent to IPv4 types and others that are unique to IPv6.
