IPv6 Security

The National Institute of Standards and Technology (NIST) has released a publication called "Guidelines for the Secure Deployment of IPv6 ."
IPv4 (the current addressing standard for the Internet) has a limited number of addresses for identifying things (computers, devices, etc.) on the Internet, and the store of unused addresses is almost exhausted. The move to a larger addressing scheme is readily admitted, but security problems need to be avoided during the move from the old to new addressing methods.
