IP-Tests / DNS Records lookup

Looks up the DNS record of a domain, supports A, AAAA, CNAME, MX, NS, TXT and SRV records.

The Domain Name System (DNS) is a hierarchical distributed naming system for computers, services, or any resource connected to the Internet or a private network. It associates various information with domain names assigned to each of the participating entities. Most prominently, it translates domain names meaningful for users to the numerical IP addresses needed for the purpose of locating computer services and devices worldwide. By providing a worldwide, distributed keyword-based redirection service, the Domain Name System is an essential component of the functionality of the Internet.

The types of resource records stored in the zone files of the Domain Name System (DNS) are called DNS record types (A, MX, SRV, SOA etc.).

The DNS implements a distributed, hierarchical, and redundant database for information associated with Internet domain names and addresses. In these domain servers, different record types are used for different purposes.
