A CAA record lookup is a process of checking the DNS records of a domain name to see if any CAA records have been set. CAA records are used to specify which certificate authorities (CAs) are allowed to issue certificates for a domain name.
This tool allows you to check CNAME records of any public domain without any hassle. The results will include the following information:

A CAA record, or Certification Authority Authorization record, is a type of DNS record that allows domain name owners to specify which certificate authorities (CAs) are allowed to issue certificates for their domains. CAA records allow domain owners to control which CAs can issue certificates for their domains, which can help to prevent unauthorised certificate issuance.
CAA records are specified in the Domain Name System (DNS) by the CAA record type. The CAA record type has two parts: a tag and a value. The tag specifies the type of CAA record, and the value specifies the information that is being provided to the CA.
The Domain Name System (DNS) is a hierarchical naming system for computers, services, and other resources connected to the Internet or a private network. It associates various information with domain names assigned to each of the participants. Most prominently, it translates easily memorised domain names to the numerical IP addresses needed for locating and identifying computer services and devices with the underlying network protocols.
DNS is a distributed system, which means that the DNS database is stored on multiple servers across the Internet. This makes it more reliable than a centralised system, as it is less likely to be affected by a single point of failure.
A DNS record is a type of resource record that is stored in the Domain Name System (DNS). DNS records contain information about a domain name, such as its IP address, mail servers, and other properties.
DNS records are an important part of the Domain Name System. They allow users to easily access websites and other resources by using domain names. DNS records also provide other important functions, such as providing information about resources, caching DNS information, load balancing, and security.
