DNS for IPV6 is just like IPV4, but longer. In part 2 I discussed DNS quad A records. Now I'll explain IPV6 PTR records.
Liberation! Using IPV6, I have 18,446,744,073,709,551,616 public IP addresses. This is considered a small offering (/64). Normally, an organization would get a /48 network that contains 65536 /64 subnets.
My email server now functions on both IPV4 and IPV6 networks. Postfix is IPV6 ready but, the configuration needed some adjustments.
This website is now dual stacked to both IPV4 and IPV6. In part four of my IPV6 series I'll tell you what I learned during this migration.
