Simple Whois Client offers you an easy way to check the Whois status of one or more domains.

Key features :
- Single Whois
- Multi Whois for up to 15 TLDs
- Supporting over 1000 TLDs

For 99% of all TLDs the RDAP protocol (successor of Whois) is used. Since many CCTLDs do not currently support RDAP, they are not supported or the old Whois protocol is used. Multi Whois Check requires mandatory RDAP for a TLD!
