A tool that allows users to find DNS (Domain Name System) records is often referred to as a "DNS lookup" or "DNS checker" tool. DNS records are used to map domain names to IP (Internet Protocol) addresses and other information, and are an important component of the infrastructure of the internet.
DNS lookup tools are commonly used for a variety of purposes, such as verifying the DNS setup of a domain, troubleshooting DNS issues, and gathering information about a domain or website. They may be available as online tools that can be accessed through a web browser, or as software programs that can be downloaded and installed on a computer.
To use a DNS lookup tool, users simply need to enter the domain name and the tool will return the DNS records for the domain, such as the A record (IP address), MX record (mail server), and CNAME record (aliases). Some DNS lookup tools also allow users to view the DNS records for specific types of records, such as TXT records (text) or NS records (name servers).
