Runs in your browser. IP math is fully local. Domains get DNS zone records (A, AAAA, CNAME, MX, TXT, NS via DNS-over-HTTPS) plus registration WHOIS; resolved A/AAAA IPs are clickable to analyze. Public IPs get WHOIS / RDAP (org, network, ASN, registry, country, reverse-DNS, abuse). MACs are resolved against a local IEEE OUI database (57k+ entries) served from this server, with online fallback via maclookup.app and macvendors.com.
