IP lookup, DNS lookup, WHOIS, port reference, speed test, URL reachability check, and MAC vendor lookup. The IP/DNS/WHOIS tabs send what you enter to public lookup services (ipapi.co, Cloudflare DNS-over-HTTPS, RDAP) to get an answer — that's unavoidable for a real lookup. Port reference and MAC vendor lookup are fully local.
