What is DNS Lookup?

DNS Lookup is a query process that shows which IP address a domain name points to and which servers it is associated with. Through this process, you can easily retrieve DNS record types such as A, AAAA, CNAME, MX, NS, TXT, and SOA for a given domain.

This tool is especially preferred by system administrators, developers, and security experts. It is used for various purposes such as checking domain redirections, verifying email server settings, and analyzing DNS configurations.

How Does DNS Lookup Work?

Using an online DNS Lookup tool is very simple:

• Type a domain name (e.g. example.com) into the search bar above.

• Press enter to go to a detailed results page showing the DNS records for that domain.

• The lookup is performed in real time without using any cache, so the results are always fresh and up-to-date.

• By default, the results page displays A, AAAA, CNAME, TXT, NS, MX, and SOA records.

• You can also choose which DNS server to query:

  • Public global DNS servers (e.g. Google 8.8.8.8)

  • The authoritative DNS server for the domain

  • Local DNS servers from different parts of the world
