DNS API and gTLD Domain Search
Search supported gTLD domain data by trademark, company, brand, product, or suspicious terms. Resolve DNS records, retrieve nameserver-hosted domain lists, query PTR and ASN data, and find observed subdomains. The daily Domain Activity added/deleted domain feeds are included.
Searchable DNS data plus daily activity feeds
The DNS API includes the daily Domain Activity added/deleted gTLD feeds and adds broader searchable DNS data. Use it to search supported gTLD domains by trademark, company, brand, product, campaign, or suspicious terms, retrieve domains hosted on a nameserver, resolve DNS records, query PTR and ASN data, and inspect observed subdomains.
This is the product to use when the daily added/deleted feed is not enough and you need to search across the supported gTLD dataset. Domain activity coverage is derived from public DNS and registry-related activity signals across supported gTLDs. ccTLD domain search is available as an experimental beta feature and is not comprehensive.

Features
gTLD Domain Search
Search across supported gTLD data for trademarks, company names, brand names, product names, campaign terms, suspicious words, patterns, or exact matches.
ccTLD Domain Search (Beta)
Experimental search across ccTLD domains. Non-comprehensive coverage. Useful for supplementary research but not suitable as a primary data source.
DNS Record Resolution
Retrieve A, CNAME, AAAA, NS, MX, and TXT records for any domain. Suitable for bulk lookups within pipelines and automated investigation workflows.
Subdomain Enumeration (Beta)
Find observed subdomains derived from TLS/SSL certificate hostnames. Useful for discovery, but not a complete DNS zone listing and not proof that every hostname is currently active.
Nameserver Search and Mapping
Search and list gTLD nameservers, and retrieve domains associated with a given nameserver. Useful for mapping hosting infrastructure and identifying shared hosting relationships.
ASN and IP Data
Retrieve the Autonomous System Number and AS Name for any IP address. Useful for mapping domain infrastructure back to hosting providers and networks.
Domain Activity Included
Daily added and deleted gTLD domain feeds are included, with monitoring for trademark, company, brand, product, campaign, or suspicious terms.
Trademark and Malware Analysis
Monitoring for trademark terms, company names, brand names, product names, and malware-related patterns across searchable gTLD and daily activity data.
