Basic Steps You need to perform the following nine steps to use IPv6 with DNS:

1. Add AAAA records in your DNS server for the hostnames of the devices that can be reached through the IPv6 protocol.

2. Add pointer (PTR) records in your DNS server for the IP addresses of the devices that can be reached through the IPv6 protocol.

3. Enable IPv6 access to the authoritative DNS servers. Be sure that TCP/53 and UDP/53 can be accessed through IPv6.

4. Enable IPv6 connectivity to the external full-service resolvers that send DNS queries to authoritative servers in the world.

5. Make sure that the full-service resolver is configured with both IPv4 and IPv6 glue for the root servers in the world.

6. Enable IPv6 on the recursive resolver so that it responds to DNS requests over IPv6 as well as IPv4.

7. Enable IPv6 on the node that sends queries so that it can send DNS requests to the recursive resolver.

8. Configure the stub resolver on the node that sends queries so that it uses IPv6 to send DNS queries, either statically or using Dynamic Host Configuration Protocol Version 6 (DHCPv6).

9. Review policies for flows and make sure that both TCP/53 and UDP/53 can be accessed over IPv4 and IPv6. These steps are discussed in more detail later in this document.
