Are you wondering which type of record you should use for your website—an A record or an AAAA record? Well, the answer depends on the version of the Internet Protocol you are using.

What is a DNS A record?

A (Address) record is a type of DNS record used to point a domain name at an IPv4 address.

All domain names registered with a domain name registrar are required to have an A record associated with them. Thus, A records are the essential building blocks of the internet, connecting domain names to their respective IP addresses. An A record is responsible for mapping a domain name to its IPv4 address. It ensuring that a user’s browser knows which server to connect to when they type in a domain name in the address bar.

When the lease on your IP address expires, your ISP (Internet service provider) can change it automatically.

If you use the device as a server, you can use DDNS to ensure it remains accessible. Otherwise, you won’t be able to reach or determine the new IP address from afar.

Without Dynamic DNS, the connection would break the moment the ISP changed the IP address, making it impossible for someone operating a monitoring server with a camera at home to observe the footage from a distance.

Check out a fantastic Dynamic DNS service!
