In this scenario, a web browser in a popular operating system is requested by the user to go to the http://www.ietf.org website, which is the main page of the IETF. The website is also dual-stack enabled, that is it has both IPv4 and IPv6 addresses in the DNS. As shown in Figure 3.32 the DNS resolver on the operating system attempts to resolve both IPv4 and IPv6 addresses of the www.ietf.org. The resolver is utilizing the 'A resource record first and then the AAAA resource record' approach of those possible and listed in Section 3.10.2. It i
