Quick answers about how this tool works.

A DNS Lookup Tool queries domain name servers to retrieve public DNS resource records (such as IP addresses, mail servers, and text records) associated with a specific hostname.

An A record maps a domain name to a 32-bit IPv4 address (e.g., 192.0.2.1), while an AAAA record maps a domain name to a 128-bit IPv6 address (e.g., 2001:db8::1).

MX (Mail Exchange) records specify which mail servers are responsible for accepting incoming email messages on behalf of your domain name, along with their relative priority weights.

A CNAME (Canonical Name) record aliases one domain name to another canonical domain. CNAME chaining occurs when a domain points to a CNAME which in turn points to another CNAME before resolving to an A/AAAA record.
