IP addresses, ASNs, DNS records, WHOIS data — everything you need to understand what's happening on the network, in one place.
Geolocate any IPv4 or IPv6 address. See city, region, country, ISP, ASN, timezone, and coordinates.
Look up any Autonomous System number — announced prefixes, peer relationships, and routing history.
Resolve A, AAAA, MX, TXT, CNAME, NS, and SOA records for any hostname in real time.
Query registration, ownership, and contact records for any domain name or IP block.
Inspect the full response headers from any URL — status codes, caching, security headers, and redirects.
Check TLS certificate details, expiry dates, issuer chain, and cipher suite for any domain.
Trace the BGP path to any prefix — origin AS, upstream providers, and route visibility across peers.
Break down any CIDR block — network address, broadcast, usable host range, and mask in binary.
Resolve PTR records for any IP address and verify forward-confirmed reverse DNS (FCrDNS).
