There is an ongoing discussion about the impact of IPv4 to IPv6 transition mechanisms such as NAT-PT (RFC2766). [NAT-PT-ISSUES] identifies several problems around the DNS ALG functionality in NAT- PT. This document proposes possible solutions to some of the problems illustrated in [NAT-PT-ISSUES] and to additional issues with the DNS ALG functionality in NAT-PT.
