Main domain Route53, delegating sub-domain to Cloudflare

[thinktomek]

I am using AWS as my hosting providers as well as there is complex DNS zone configuration for my root domain. domain.com. I want to leave my domain.com in Route 53 / AWS.

I’ve got a service: service.domain.com which needs CDN, hence I’ve tried to set up Cloudflare account and add the: service.domain.com.
Unfortunately I am getting an error: “Please ensure you are providing the root domain and not any subdomains (e.g., example.com, not subdomain.example.com) (Code: 1116)”

… so I’ve tried to add the domain.com and added the NS entries for my service.domain.com, so they point to Cloudflare.
Unfortunately this doesn’t seem to be working.

Is it possible to use Cloudflare service for sub-domain without moving root zone of a domain to Cloudflare?

I don’t think you can delegate in…only out.

Delegating only a third level zone (a.b.com) to cloudflare

I am in the process of trying out Cloudflare. I host my own DNS (b.com), and I have created a distinct third level zone (a.b.com). I put glue records in the b.com zone and setup the a.b.com zone in its own separate file. (I am using BIND on linux boxes). Testing this on intodns.com gives a green light (save for a “WARNING: Looks like the parent servers do not have information for your TLD when asked. This is ok but can be confusing.”) However when I try to add this zone to Cloudflare’s control…
