Domain Registration and Nameservers

These tools look at a domain itself rather than one record. WHOIS Lookup shows the registrar, dates and status from RDAP data, Domain Expiration Checker handles up to ten domains at once, NS Lookup lists nameservers and the SOA record, and DNSSEC Checker shows whether the zone is signed.
