My current DNS that is apart of the hosting package can take anywhere from 1-12 hours to update the DNS servers of changes I made. On the other hand Amazon Route 53 changes are reflected within 60 seconds. Now I call that fast DNS. I am thinking of changing my DNS to them for all my domains. They charge .50 cents per zone and .50 cents per million queries a month.
All I have to do is find a way to have some of the DNS entries auto update for my dynamic address for my home servers and I’ll be good to go. I think I found a script online. Once I get it working I will update this post.
