Can we maintain DNS records of a particular domain from different places?

Question

I have bought a domain from BigRock and there are some DNS record entries in BigRock. And I'm using AWS Route53 service (DNS Service only) for the above domain and was maintaining some different records.

Is this doable?

If yes, what will happen if I have same DNS record entries at both places, does the request go to entry in BigRock or to the entry in Route53?

If no, what will happen if I add the Nameservers created by Route53 (during the creation of Hosted Zone) in BigRock and keeping the existing Name servers provided by BigRock?

Please add in your detailed explanation

Answer 1

Route53 is DNS management service, delegating specific domain from Bigrock to Route 53 allows the ability to create dynamic environments with the tools provided by Amazon Web Services. Once you delegate to AWS, you cannot control your DNS from Bigrock.

You can also delegate a specific sub-domain to be managed by route53. For example, sub-domain mail.example.com can be delegated to route 53, while the parent domain example.com can be managed from BigRock.
