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.
≈ marks an estimate; all counts update as zones import.
Lines are 7-day averages; dots are each day's total. On shaded days a large zone had no update, so that day runs low and the next one high.
