I have a newbie question about DNS records.
I have one server which I'm hosting a handful of sites on. Currently, each site has it's domain hosted by an independent provider and each has an A record pointing to the server's IP address.
But if I want to change the server in the future, I will have to go back an update each IP address in each DNS record.
Is it possible to use a CNAME record on each domain to point to another domain that I control directly? This is so I can update the IP address in 1 place myself and not have to get all these other DNS providers to update their records separately?
Sorry if this is a duplicate question but I couldn't seem to find one that answers this problem directly in a way I understand.
