DNS Services for a registrar

My big concern would be the current lack of v6 support on AWS for such a deployment.  I suspect it?s coming soon as they just announced IPv6 support on S3 yesterday.

How many zones do you expect to scale to?  I?ve been running a free secondary DNS service for many years on BIND, but moving to something else makes a lot of sense these days.

Do you have a lot of DNS server experience in-house?  There?s a lot of little things that come up along the way.  You really should consider being subscribed to the dns-operations list and asking there as well.

I like having good control over my own fate, so would prefer running my own service, but plenty of people use hosted DNS at their providers, and there?s plenty of folks who can sell you a service from dyn to neustar with their own cost models.

I would either provide a completely opaque service offering where you retain control of the NS records so can easily move/renumber as you scale up, or consider a solution which can be expanded globally as needed over time.  

I?m able to host ~10k zones in my free secondary service without issues, but to ?take the next step? requires decoupling 20 years of history I?m dragging around.
