Anycast DNS is a form of communication or routing technology that allows you to send and receive data quickly. One IP address can be entered into several DNS servers around the world using this method. Any of them has the ability to react to the request. The goal is for the server that is nearest to the user in terms of distance to respond. This significantly speeds up the response time.
Dynamic DNS, also commonly called Dyn DNS or DDNS, is a great technology that helps with auto-updating the name servers. Every time when the IP address (IPv4 or IPv6) changes for some reason, that beneficial service is going to refresh the DNS records – A record and AAAA record.
