IP WHOIS (now often RDAP) shows which organization holds an IP block, allocation dates, and abuse contacts for reporting misuse.

Is IP WHOIS the same as domain WHOIS?

No. Domain WHOIS covers registrar data for names. IP WHOIS covers network allocations from Regional Internet Registries.

How do I report abuse?

Use the abuse email or contact from IP WHOIS results when reporting spam, scanning, or attacks from an IP.

RDAP is structured JSON with consistent fields; many registries replaced legacy WHOIS text for IP data.

No. It shows network operator contacts, not the physical location of an individual user behind NAT.
