I don't know DNS provider

I don't know DNS provider

I bought a domain name through zoho.

After I made the payment and tried to start configuring the email account linked to the domain I have just bought, I was asked to verify the domain and, to do so, I must do some configurations on my DNS provider.

But, I DON'T KNOW who sold me the domain name because I did it all through zoho!!!!!!

I'm so desperate because I need that domain working as soon as possible!!!!

Please help me!!!!

Btw, the domain is called lischen-roscella.com
