Unable to connect Godaddy Domain

Question

Hello Railway Support Team,

I am currently configuring my custom domain [**waabooking.com**](http://waabooking.com) and would like to ensure I am using the correct DNS setup for your platform.

At the moment, I have configured:

* An **A record** for the root (@)
* Planning to add a **CNAME for www** pointing to my Railway app

However, I need clarification on the following:

1. Does Railway provide a dedicated **IP address** for root domain (A record), or should I only use a CNAME-based setup?
2. If an A record is required, what is the correct IP address I should point [**waabooking.com**](http://waabooking.com) to?
3. Is it recommended to use:  
   * Root domain ([waabooking.com](http://waabooking.com)), or  
   * Subdomain ([www.waabooking.com](http://www.waabooking.com)) with CNAME to Railway?
4. Are there any additional required records (TXT, ALIAS, ANAME, etc.) for proper verification and SSL provisioning?
5. Do you recommend redirecting root → www for best compatibility with Railway?

My goal is to ensure:

* Proper DNS resolution globally
* Successful domain verification
* SSL certificate provisioning without issues

Please provide the exact recommended DNS configuration for Railway so I can align my setup accordingly.

Thank you for your support.

Kind regards,  
Bipin
