This document describes how NAT64 and 464XLAT can be deployed in an IPv6 operator (cellular and broadband) or enterprise network and the issues to be considered when having an IPv6-only access link, regarding: a) DNS64, b) applications or devices that use literal IPv4 addresses or non-IPv6 compliant APIs, and c) IPv4-only hosts or applications.
