Domain Name System Client Behavior in Windows Vista

Overview

Microsoft Windows Vista includes both Internet Protocol version 4 (IPv4) and Internet Protocol version 6 (IPv6) protocol stacks that are installed and enabled by default. Domain Name System (DNS) name queries and registrations can now involve both IPv4 address records (A records) and IPv6 address records (AAAA records). This paper describes the behavior of the DNS Client service in Windows Vista for DNS queries and registrations and the possible impact on DNS traffic.
