Step 4: Add DNS Records:
Inside the hosted zone, you can create various DNS records. Common ones include "A" records (to point to IP addresses) and "CNAME" records (to alias one domain name to another).
Step 5: Update Nameservers:
If you registered your domain outside AWS, update your domain's nameservers to the ones provided by Route 53 in your hosted zone.
Step 6: Health Checks (Optional):
Set up health checks to monitor the availability of your application. If the primary resource fails, Route 53 can reroute traffic based on these checks.
Step 7: Test Your Domain:
Type your domain into a web browser or use tools like nslookup to ensure it resolves correctly.
Step 8: DNS Record Types and Their Uses:
A Record (Address Record):
Purpose: Points a domain or subdomain to an IPv4 address.
How It Works: When users access your domain, the A record directs them to the correct IP address.
Use Case: Mapping your domain like "example.com" to the IP address of your web server.
AAAA Record (Quad-A Record):
Purpose: Points a domain or subdomain to an IPv6 address.
How It Works: Similar to the A record, but for IPv6 addresses.
Use Case: Mapping your domain to the IPv6 address of your web server, especially important as IPv6 adoption grows.
CNAME Record (Canonical Name Record):
Purpose: Aliases one domain name to another.
How It Works: When users access a domain, the CNAME record redirects them to another domain.
Use Case: Pointing "www.example.com" to "example.com" or directing a subdomain to an external platform like "shop.example.com" to an e-commerce platform.
MX Record (Mail Exchange Record):
Purpose: Specifies the mail servers responsible for receiving email messages for a domain.
How It Works: Directs emails sent to your domain to the appropriate email servers.
Use Case: Setting up email services for your domain.
