DNS Coffee collects and archives DNS zone files every day, building a history of the DNS itself: when each domain, nameserver, and IP first appeared, what it points at now, and everything in between — across the root and 1,200+ TLD zones since 2011.
Search any domain, nameserver, IP, or subnet; browse the daily change feeds and trends; or dig in programmatically with the API.
≈ counts are estimates and update as zones import.
