DNS and Domain ToolsThree tools
- DNS lookup: the records of a name: addresses, mail servers, name servers, text records.
- Domain lookup: the registrar, dates, name servers and status of a registered domain.
- Domain name check: which extensions already have a registration record for a name.

_dmarc. - You are choosing a name: use the name check, then confirm at a registrar.
Does it show my private details?
