I've been looking at the membership page and I noticed that when I hover over the "?" next to "Your domain name" it states that if I register my domain with Dynu it includes unlimited dns services. Does this mean if I register my domain with Dynu that the 14.99/year price for the domain includes all the benefits of the 9.99/year membership?

If not, what exactly does "unlimited dns services" mean?

Thanks in advanced for your help.
