Testing nameserver configuration using it
I'm thinking to leave my hosting provider NS's for Route53 (amazon distributed nameserver) for several reasons (and since I cannot update them directly but I have to ask them that will accomplish the request in a week).
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 "play" with hosted zone is there a way I can test the name resolution settings before to make the domain point to the new nameserver, risking to obscure my website?
I'm not sure if the last dot in CNAME records is necessarly or not...
