Complete IP Toolkit
Everything you need to investigate, monitor, and understand IP addresses and network infrastructure — in one platform.
IP Geolocation
Pinpoint any IP to city-level accuracy. Country, region, city, postal code, coordinates, and timezone — updated daily from multiple data sources.
DNS Lookup
Query A, AAAA, MX, NS, TXT, CNAME, SOA, and SRV records. Check propagation status across global resolvers in seconds.
WHOIS Intelligence
Full domain and IP registration data. Registrar, creation date, expiry, nameservers, and registrant details parsed into clean JSON.
Traceroute
Visual network path analysis showing every hop, latency, and ASN. Identify bottlenecks and routing issues from multiple vantage points.
Blacklist Check
Scan IPs against 100+ RBL/DNSBL databases simultaneously. Identify reputation issues before they impact email deliverability.
SSL Certificate Check
Validate SSL/TLS certificates, chain of trust, expiry dates, cipher suites, and protocol support. Catch misconfigurations early.
Reverse DNS
Resolve IPs back to hostnames. Validate PTR records, identify shared hosting neighbours, and verify mail server configurations.
Port Scanner
Fast, non-intrusive port scanning across common service ports. Identify open services, detect unexpected exposure, and verify firewall rules.
ASN & BGP Data
Autonomous System lookups with prefix announcements, peering data, and network ownership. Understand the routing landscape.
Threat Intelligence
Cross-reference IPs against threat feeds, tor exit nodes, known proxies, and VPN endpoints. Risk scoring for security teams.
ISP & Network Detection
Identify the Internet Service Provider, organisation, connection type (fibre, mobile, satellite), and hosting provider for any IP.
Bulk Analysis
Process thousands of IPs in a single API call. CSV upload, batch processing, and exportable reports for large-scale investigations.
Three Steps. Instant Intelligence.
From query to actionable data in under 50 milliseconds.
Send a Query
Pass an IP address, domain, or hostname to any endpoint via our REST API. Simple GET requests with your API key.
GET /api/v1/lookup/8.8.8.8We Analyse
Our distributed edge network queries multiple authoritative sources in parallel — geolocation databases, DNS resolvers, WHOIS registries, and threat intelligence feeds.
12 sources queried in parallelGet Results
Receive a structured JSON response with every detail — location, ISP, threat score, DNS records, certificates, and more. Ready to use in your application.
