WHOIS provides ownership and registration information for IP addresses. It's an essential tool for network administrators, security researchers, and anyone dealing with IP addresses.
Що таке WHOIS?
WHOIS is a query-response protocol for accessing registration information about IP addresses and domain names. For IP addresses, Regional Internet Registries (RIRs) maintain WHOIS databases.
Each RIR operates its own WHOIS service: RIPE (Europe), ARIN (Americas), APNIC (Asia-Pacific), AFRINIC (Africa), and LACNIC (Latin America).

WHOIS for Leased IPs
