I own a domain, managed by my "registrar". I also have a VPS, managed by my "hoster" (e.g. DigitalOcean, etc.)
I want to use the hoster's DNS services, so:
- I must change the NS records (in the registrar's zone file) from those of the registrar to those of the hoster
- My zone file contains many other records (A, MX, TXT, etc.), so I assume I must recreate them in the hoster's zone file
Must I remove those records from the registrar's zone file? What will happen if I leave them?
