Search observed DNS relationships across FQDNs, IP addresses, CIDR prefixes, ASNs, registered domains and public suffixes. Pivot through connected infrastructure and export results by CSV, JSON or API.
What are you investigating?
Look up an FQDN and inspect observed DNS records, IP addresses, prefixes, ASNs, record types, TTLs and observation dates.
No FQDN records to summarize.
Use one interface for FQDN, reverse IP, CIDR prefix, ASN, registered-domain and public-suffix search. Start with any supported entity, pivot through observed relationships, visualise connected infrastructure and export the result set.
Search an IPv4 or IPv6 address to find FQDNs observed on that address, then pivot to its CIDR prefix, ASN, registered domains and related infrastructure. This is based on observed FQDN-to-IP relationships rather than relying only on PTR records.
Look up a fully qualified domain name to inspect observed IP addresses, prefixes, ASNs, DNS record types, TTLs and observation dates. Search a registered domain to discover observed hostnames beneath it and optionally narrow the results to a hostname branch.
Search an autonomous system number or IPv4/IPv6 CIDR prefix to find observed hostnames associated with that network infrastructure. Zoneshift also supports ASN details, announced subnet lookup, owner or handle search, and ASN resolution from an IP address.
Compare observed domain counts across top-level domains and multi-label public suffixes. Use the Visual Explorer to graph relationships between FQDNs, IPs, prefixes, ASNs, registered domains and public suffixes, or automate searches through the documented API.
Read the Zoneshift API reference for request parameters, pagination, response fields and code samples.
Explore observed domain counts by public suffix, including top-level domains such as .com and multi-label public suffixes such as github.io. Filter, compare and export the results.
Filter and compare observed public suffix counts.
Seed the graph with an FQDN. The graph shows observed links across ASN, prefix, IP, FQDN, registered domain, and TLD/eTLD.
