DNS redirection via route 53 hosted zone

When working with Amazon Route 53 hosted zones, it's important to understand that while you can delete name servers, you cannot directly add new ones. This is by design and relates to how Route 53 manages DNS for your domains.

When you create a hosted zone in Route 53, it automatically assigns four name servers to that zone. These name servers are fundamental to the functioning of your DNS configuration and are managed by AWS to ensure reliability and performance.

The ability to delete name servers from the NS (Name Server) record in your domain's DNS configuration is provided to allow you to update or change your DNS service provider. However, adding new name servers is not possible because Route 53 needs to maintain control over the authoritative name servers for your hosted zone.

If you need to change the name servers for your domain, the correct process is to:

1. Create a new hosted zone (if necessary).
2. Update your domain's registration to use the new name servers provided by Route 53 for the new hosted zone.
3. Delete the old name servers from your domain's NS record at the registrar level.

This process ensures that your domain always points to the correct, AWS-managed name servers for your Route 53 hosted zone. It's a security and consistency measure to prevent potential conflicts or misconfigurations that could arise from manually adding name servers.

Remember, when working with Route 53, you should always use the name servers provided by AWS for your hosted zone, and update them at the domain registrar level when changes are needed.

I think your getting confused with the Registrar DNS Glue Servers and the NS records in a Zone.

If your moving to a different DNS Hosting provider, you need to update the Glue Records with your registrar.

You cant "redirect" my updating NS records. NS Records are assigned when you create a Hosted Zone in Route 53
