Robtex is a comprehensive DNS and network intelligence platform founded in 2002, providing detailed information about IP addresses, domains, and autonomous systems. Used by network administrators, security researchers, and IT professionals worldwide, Robtex offers deep visibility into internet infrastructure and relationships.
The platform provides DNS lookups with full record details (A, AAAA, NS, MX, TXT, SOA), reverse DNS, WHOIS data, BGP routing information, and network topology visualization. Robtex is particularly known for its ability to show relationships between domains, IPs, and nameservers, helping users understand infrastructure connections and identify potential security issues.
Robtex's data comes from continuous DNS crawling, BGP route collection, and integration with external data sources including Tranco rankings, Majestic backlink data, and threat intelligence feeds. The platform maintains historical data allowing users to track changes in DNS and network configuration over time.
The service runs on a globally distributed infrastructure with edge servers for fast response times. Robtex uses its own recursive DNS resolver infrastructure for accurate, real-time DNS data. The platform offers both free web access and API services for programmatic queries, making it valuable for both manual investigation and automated security workflows.
