DNS Records can also be used to retrieve mail exchangers, the SOA record of the domain, DNSSEC records, reverse lookups, and other data depending on the configuration of the DNS server. You can get all this data with a simple API called nslookup.
Don’t know what is an API? An API (Application Programming Interface) is a software component that allows two separate software components to interact with one another. The API acts as a “translator” that allows two different systems to exchange information. In general, you don’t need to understand how this communication happens; it’s enough that the API exposes the functionality you need in a way that you can use it in your code.
There are many APIs that allow you to check domain names and IP addresses.
