Testing nameserver configuration using it
I'm thinking of changing from my hosting provider nameservers to Route53 (Amazon's distributed nameserver) for several reasons.
I'm currently setting all records like they are on my current host page (I can see my DNS settings but I cannot change them). Since I'm not used to working with Route53's hosted zones, is there a way I can test the new nameserver resolution settings before updating the domain to point to the new nameserver?
For example, I'm not sure if the last dot in CNAME records is necessary or not...
