When moving web server to new droplet will DNS find it and update records automatically?
I have a DigitalOcean “Droplet” test server that is running PHP5.3. Yesterday I created a new test server Droplet running LAMP with PHP7.0 and set it up with the same Domain Name as the PHP5.3 Droplet. Then I turned off the PHP5.3 Droplet. Since the new PHP7.0 Droplet uses the same Nameservers, will the DNS system realize that the IP Address has changed for that Domain Name? Or is there something I need to do to nudge the DNS system to do this update?
