It seems like inbound and outbound zone transfers aren't offered by a number of providers (like AWS). Do you know of a list of DNS providers that support either option?

I used to use these two services together do this:

  https://puck.nether.net/dns
  https://acc.rollernet.us/

They're both free to sign up, provide free secondary DNS, zone transfers and fully support IPv6.

I only stopped using them because I wanted to run my own DNS service.

EasyDNS provides integration with AWS: http://easyroute53.com/

They have an interesting blog post about setting up secondary DNS: http://blog.easydns.org/2013/09/10/what-we-are-doing-about-c...

I have no affiliation with them, just a happy customer.

A search for "secondary DNS service" should give you several results.

My research into it is from a "manage your DNS records internally, then use a couple of providers for all public facing responders". In that situation all you need them to support is inbound transfers, which several do.
