Cisco IPv6 Solutions

The current IP address space is unable to satisfy the potential huge increase in the number of users or the geographical needs of the Internet expansion, let alone the requirements of emerging applications such as Internet-enabled wireless devices, home and industrial appliances, Internetconnected transportations, integrated telephony services, sensors networks such as RFID, ZigBee, and distributed computing or gaming.

IPv6 quadruples the number of network address bits from 32 bits (in IPv4) to 128 bits, which provides more than enough globally unique IP addresses for every networked device on the planet. The use of globally unique IPv6 addresses simplifes the mechanisms used for reachability and end-to-end security for network devices, functionality that is crucial to the applications and services that are driving the demand for the addresses.
