Hi

I was hoping to get your thoughts on pros and cons using name servers or A-Record.

If pointing domains to Digital Ocean's name servers and using this tutorial https://www.digitalocean.com/community/tutorials/how-to-set-up-a-host-name-with-digitalocean then I can control my clients MX-record and change the IP (as long as my clients are using Digital Ocean's name servers) incase I need to move my droplet. This is very smart and helps remove a lot of eh?? from my clients. They just need to set it once and that is it.

What are the downside of doing it this way? I believe it is faster (no NS look-up) when pointing domain to a-record directly from the registrar. Am I correct in believing that?

Besides speed what are the pros/cons of using name servers instead of A-record?

Thanks for your feedback.
