    abstract =  {Due to specific problems, NAT-PT was deprecated by the IETF as a mechanism to perform IPv6-IPv4 translation. Since then, new efforts have been undertaken within IETF to standardize alternative mechanisms to perform IPv6-IPv4 translation. This document evaluates how the new translation mechanisms avoid the problems that caused the IETF to deprecate NAT-PT.},
