What will happen if the domain name register enes from two different servers?

Question

Domain name market

There is a good project that lies with a stupid hoster, an urgent move to new servers to another hoster is needed, but stopping the site even for an hour will ruin the project. How to move to another hosting in the minimum time. As far as I know, enes can be re-registered in 72 hours

Answer 1

hm. yeah simple. locate the site at the new host and change the A record to the ip of the new host in the DNS management interface. thus, clients whose dns is updated earlier will go to a new hoster, those that have not updated will go to the old one, but in 1-2 days the dns of clients and their providers will be completely updated and everything will go to the new hoster.
