WHOIS
WHOIS is a protocol that provides information about domain names and IP addresses. It reveals registration details, ownership information, contact details, and administrative data for domains and IP blocks.
What it shows:
- • Domain registration and expiration dates
- • Registrar information and contact details
- • Name servers managing the domain
- • Domain status and security settings (DNSSEC)
- • IP address ownership and organization
- • Abuse contact information
Common uses:
- • Check domain availability and ownership
- • Find contact information for domain issues
- • Verify domain registration status
- • Investigate IP address ownership
- • Report abuse or security issues
How it works: Queries WHOIS databases maintained by registrars and regional internet registries (RIRs). Different databases store information for domains vs IP addresses, with varying levels of detail and privacy protection.
