How to find out A record?

I’ve been trying to change the domain of the Website I made. I bought a new domain from an other provider. The provider needs an A record to be able to change the domain of my website. How can I find the A record? Or is there any other way to change the domain? Any help is appreciated!

Have you added the domain name to an account already? If not, you need to do so first. And to do that, you need to change the nameservers of your domain name.
