DNS Settings are the records that define how your domain or subdomain is accessed on the Internet via IP addresses (A/AAAA Records) and/or various other settings.
DNS stands for Domain Name System and is responsible for assigning a domain name to an IP address. This has the advantage that Internet users only need to enter a domain name (such as 1and1.com) in their browser when visiting a website, blog, etc. instead of remembering each corresponding IP address (such as 184.108.40.206).
There are several DNS settings that make it possible for this to work smoothly, each of which manages different aspects of the domain's usage.
When setting up a IONOS domain, there are a number of settings to choose from. To keep it simple, you can just follow the recommendations we provide for you along the way. These will help ensure that you are using the correct settings from the beginning.
