Networking & Internet
Understand the network behind any request. Look up IP geolocation, detect VPNs and proxies, inspect ASN data, query WHOIS and DNS records, and check MX configuration — all the tools you need to validate, investigate, and secure traffic at the network layer.
IP Geolocation
Get geolocation data for any IP address including country, city, ISP, and VPN detection.
ASN Lookup
Look up Autonomous System Number (ASN), organization, ISP, and network route information for any IP address.
VPN & Proxy Detection
Detect if an IP address belongs to a VPN, proxy, Tor exit node, or hosting provider. Returns threat scores and fraud indicators for fraud prevention and risk assessment.
WHOIS Lookup
Get domain registration details including registrar, name servers, status, creation and expiry dates, and DNSSEC information.
Domain Info
Look up DNS records and check domain availability. Returns A, AAAA, MX, NS, TXT, and CNAME records alongside a registration availability flag.
MX Lookup
Look up MX (Mail Exchange) records for any domain. Returns all mail server hostnames with their priorities, sorted from highest to lowest priority.
Disposable Domain Checker
Check whether an email domain belongs to a known disposable or temporary email provider. Use this for targeted domain lookups. For full email validation including syntax, MX records, and normalization, see the Email Validator.
