Here you can query the available data for a domain.
In addition to the data for the given domain name the query will also try to get the TXT record for DMARC, the SRV records for the mail server configuration (see RFC6186) and the record for “www.” if the domain name is not a sub domain.
Due to the way how DNS works, it is not possible to determine all existing records for other names/subdomains automatically. These have to be checked manually (e.g. “test.domain.example” for the record “test” in the domain “domain.example”).
