# Hybrid DNS Setup

# Hybrid DNS Setup: Delegating Subdomains Between Route 53 and Cloudflare 🌐

Are you looking to optimize your DNS management by using both AWS Route 53 and Cloudflare? This guide walks you through a hybrid DNS configuration where your main domain is managed by one provider (e.g., Route 53) while delegating a subdomain to another (e.g., Cloudflare). You can also reverse this setup to suit your needs!

### **Scenario 1: Main Domain with Route 53, Subdomain with Cloudflare**

1️⃣ **Configure Route 53 as Your Primary DNS Provider**

* Set up or update your hosted zone for the main domain (e.g., `example.com`) in AWS Route 53.
* Ensure all required DNS records (A, CNAME, MX, etc.) for your main domain are correctly configured.

2️⃣ **Delegate the Subdomain to Cloudflare via Route 53**

* Create an NS (Nameserver) record in Route 53 for the subdomain (`sub.example.com`).
* Point this NS record to the Cloudflare nameservers for the subdomain. This allows Cloudflare to handle DNS queries for `sub.example.com`.

3️⃣ **Set Up Cloudflare to Manage Your Subdomain**

* Log in to Cloudflare and add the subdomain (`sub.example.com`) as a new site.
* Configure the necessary DNS records in Cloudflare for the subdomain.

🔄 **With this setup, Route 53 manages the main domain, and Cloudflare handles all DNS queries for the subdomain.**

### **Scenario 2: Main Domain with Cloudflare, Subdomain with Route 53**

1️⃣ **Set Cloudflare as Your Primary DNS Provider**

* Add and configure your main domain (`example.com`) in Cloudflare.

2️⃣ **Delegate the Subdomain to Route 53 via Cloudflare**

* In Cloudflare, create an NS record for the subdomain (`sub.example.com`).
* Set this NS record to point to Route 53’s nameservers for the subdomain, ensuring DNS queries are routed to AWS.

3️⃣ **Use Route 53 to Manage Your Subdomain**

* Create a new hosted zone in Route 53 specifically for `sub.example.com`.
* Configure all necessary DNS records for the subdomain in Route 53.

🔄 **In this configuration, Cloudflare manages the main domain while Route 53 handles DNS queries for the subdomain.**

### **Key Points to Remember:**

* Ensure only one DNS provider manages queries for each domain or subdomain to avoid conflicts.
* Allow time for DNS changes to propagate fully to prevent temporary resolution issues.
* This flexible approach lets you leverage the unique advantages of both Route 53 and Cloudflare.

> By implementing a hybrid DNS setup, you can efficiently manage DNS configurations and take advantage of both AWS and Cloudflare’s capabilities.
