Should DNS be configured with DO or with the Domain Registrar?

My domains are registered with Hover.

It looks like I can configure my DNS details at Hover (with nameserver being DO).

And almost the exact same config options show up in DNS settings for DO.

So, should I be configuring them in one or the other or both? (And why please?)

(Note: In case this detail is needed: I’m trying to set up MX records for a MailServer that will manage email for 4 domains that are set up on a single Droplet via Apache Virtual Hosts. I’m on Ubuntu 14.04.)

This question was answered by @saurabh:

DNS is the first point of entry to your domain. It will inform the requestor to route it’s connection to correct IPs. For example, your A-record informs the requestor where your domain website resides. Similarly, your MX-record informs the requestor where your email exchange resides.

If hardly matters where you host your DNS however, it may so happen that you would want to use certain features of the DNS host and you would want to go with it. Other than that, it is DNS host, with same functions as explained above!

Hope this helps!
