What is a DNS Lookup?

The DNS record checker tool helps you conduct a DNS record lookup for your domain, but what is a DNS lookup? A DNS lookup is a request for information about a domain name. 

When you enter a website’s URL in your browser, you’re performing a DNS query request on that domain. A DNS lookup is what happens when your computer asks the Domain Name System (DNS) for the IP address associated with that domain name.

What is a DNS Lookup

Types of DNS Record Lookups

These are the main types of DNS lookups:

  • Recursive:

    A recursive DNS lookup returns all records associated with the domain name, including any subdomains.

  • Non-recursive:

    A non-recursive DNS record lookup only returns records for the specified domain name itself.

  • Forward:

    Forward lookup, which uses a domain name to find an IP address.

  • Reverse:

    Finally, the reverse DNS record lookup looks up an IP address in order to find its corresponding domain name
