Free IP Address & Domain Lookup
Search any public IP address or domain name and get detailed network information including geolocation, Autonomous System Number (ASN), network prefix, DNS records, SSL/TLS certificate details, email security records and registration information.
IP-Tracker.eu is a free network intelligence and troubleshooting tool. No registration or API key is required.
What You Can Look Up
ASN & Network Information
Autonomous System Number, organization, announced prefix, RIR information and routing data.
DNS Records
Live A, AAAA, MX, NS, TXT and SOA records for domain names.
SSL/TLS Certificate
Certificate issuer, subject, validity period, expiry status and Subject Alternative Names.
Email Security
SPF and DMARC DNS records used to help protect domains against email spoofing and phishing.
WHOIS / RDAP
Registrar, registration and expiration dates, nameservers, network ownership and RDAP information.
How It Works
1. Choose an IP address or domain
Enter an IPv4 or IPv6 address such as 8.8.8.8, or a domain name such as example.com.
2. Run the lookup
The tool combines local databases with live DNS, RDAP, routing and TLS queries.
3. Review the results
Results are grouped into geolocation, network, DNS, security, certificate and registration sections.
Data Sources
IP-Tracker.eu combines several independent data sources instead of relying on a single lookup provider.
- MaxMind GeoLite2 — local IP geolocation and ASN databases.
- BGPView — network prefix, ASN and routing information.
- RDAP / IANA — IP and domain registration information.
- DNS — live A, AAAA, MX, NS, TXT and SOA queries.
- TLS handshake — live SSL/TLS certificate information.
- RestCountries — additional country metadata.
Frequently Asked Questions
What is an IP address?
An IP address is a numerical identifier used by devices communicating over Internet Protocol networks. IPv4 addresses look like 192.0.2.1 while IPv6 uses a much larger address space.
What is an ASN?
An Autonomous System Number identifies an independently operated network participating in Internet routing. ASNs are used with BGP to exchange routing information between networks.
What DNS information can be checked?
Domain lookups can show IPv4 and IPv6 addresses, mail servers, authoritative nameservers, TXT records and SOA information.
Is IP geolocation exact?
No. IP geolocation is an estimate. Country-level results are generally more reliable than city-level results, and VPNs, proxies, mobile networks and centralized ISP gateways can affect the reported location.
Is IP-Tracker.eu free?
Yes. The public lookup tool is free to use and does not require registration.
