Lookup & verification tools

Query public registries and run network checks — domain, network, business identifier, vehicle, device. Each tool hits the canonical source (WHOIS, DNS, vPIC, NPPES, FCC, IEEE OUI…), in real time.

WHOIS lookup

Look up domain registration records.
DNS lookup

Query A, AAAA, MX, TXT and more.
SSL certificate checker

Inspect a site’s TLS certificate.
HTTP header checker

Inspect a URL’s response headers.
IP address lookup

Geolocate an IP and find its network.
Reverse DNS lookup

Find the PTR hostname of an IP.
NPI lookup

Look up US healthcare providers.
FCC ID lookup

Decode an FCC ID and find records.
EIN lookup

Validate and decode a US EIN.
Email validator

Check syntax, MX and disposable domains.
MAC address lookup

Find the vendor behind a MAC address.
IBAN validator

Validate an IBAN and decode it.
SWIFT / BIC lookup

Validate and decode a SWIFT/BIC.
ASN lookup

Look up an autonomous system number.
VIN decoder

Decode a vehicle VIN (NHTSA data).
WMI lookup

Decode a VIN’s manufacturer code (first 3 chars).
NAICS code lookup

Search 2022 NAICS industry codes by keyword or number.
LEI lookup

Search the GLEIF database by Legal Entity Identifier or name.
OBD-II code lookup

Decode a car diagnostic trouble code (P0420, P0300…).
ISBN lookup

Validate, convert and decode an ISBN-10 or ISBN-13.
Routing number lookup

Validate an ABA routing number and decode its Federal Reserve district.
Area code lookup

Find the location and time zone of any North American area code.
HS code lookup

Search Harmonized System (HS 2022) codes for traded goods.
DOI lookup

Resolve a DOI to its title, authors and journal via CrossRef.
NDC lookup

Decode a US National Drug Code and find its openFDA record.
What is my IP address

See your public IP, location and network.

Network vs. dataset lookups

For domains and infrastructure: WHOIS, DNS, SSL, HTTP headers, IP geolocation, reverse DNS and ASN all hit live data. For verification of an identifier you already have: VIN (NHTSA), NPI (CMS), EIN (IRS prefix), FCC ID, IBAN, SWIFT/BIC, MAC vendor and email. These are starting points, not final authorities — always cross-check with the source before relying on the result for material decisions.

Frequently asked questions

Are these lookup tools really free?
Yes. Every lookup is free, needs no sign-up, and queries the canonical public registry behind the data — WHOIS, DNS, NHTSA vPIC, CMS NPPES, FCC, IEEE OUI and others.
Where does the data come from?
Each tool says so on the page. Network lookups (WHOIS, DNS, SSL, HTTP, IP) hit the live protocol/server through our same-origin proxy. Dataset lookups (NPI, VIN, FCC, MAC vendor, ASN) hit the official public registry.
Are my queries logged?
No. Searches are proxied through our server but not stored — see the per-tool privacy lines for confirmation.
