Updates to DNS Coffee: new pages, new features, and changes to the API.
Jul 20, 2026
You can now search IPs by subnet: enter CIDR notation in the search box (e.g. 205.251.192.0/18) to list every stored IP in the block — each with its seen dates and active nameserver count — on a dedicated page like /ip/205.251.192.0/18. Large subnets show a clickable density map of their child blocks to drill down, and every page links to its parent and neighboring subnets. Subnets down to /16 (IPv4) and /32 (IPv6) are supported, and the same data is available from the v1 API at /api/v1/ip/{ip}/{prefixlen} (with the density rollup at /blocks).

DNS Coffee now has an FAQ covering data sources, takedown requests, and how to get API access, along with this News page for tracking changes to the site and the API.
Jul 19, 2026
The current v1 API is live, built on OpenAPI 3.1 with self hosted documentation at api.dns.coffee/doc. It serves everything the older API did, plus:
The previous API version keeps working but is now deprecated. New integrations should use v1.

The home page now leads with live collection totals for domains, nameservers, IPv4 and IPv6 records, zones, and imports, each linking to its section. Below them are full history growth charts for the root zone and the internet as a whole, with range buttons to focus on recent activity.
Jul 18, 2026
The TLDs page has a new chart showing how many domains each TLD adds per month, with the current partial month prorated so the latest point is comparable to the rest.
Jul 17, 2026
The new Feeds page shows the domains and nameservers added and removed across all zones each day, including a truly new count that ignores names that merely reappeared. A history graph tracks the daily volume over time.
Jul 17, 2026
Nameserver pages gained a domains over time history graph and a list of related nameservers found through shared parent domains and shared IP addresses. The nameservers page now ranks the most used nameservers across the whole dataset.
Jul 16, 2026
Search now matches domains and nameservers by any substring of the name, shows exact matches at the top of the results, and produces shareable result URLs. A quick lookup path like /q/example.com jumps straight to a domain, nameserver, IP, or zone when the term matches one exactly.
