What is DNS / WHOIS?
This tool gathers in a single query a domain's DNS records —A, AAAA, MX, TXT, NS, CNAME and SOA— and its WHOIS data: the registrar, the creation, update and expiry dates, and the nameservers. So you can check at a glance how a domain is configured and who it belongs to.
DNS resolution is done via DNS over HTTPS from the Cloudflare edge, so it is fast and independent of your network's resolver, and WHOIS data is fetched via RDAP, the modern, structured protocol that replaces classic WHOIS. It is perfect for diagnosing mail problems (MX), verifying verification records (TXT) or checking when a domain expires.
Frequently asked questions
Is it free?
Yes, all NewKit tools are completely free.
How does it work without installing anything?
The tool runs on Cloudflare Workers at the edge: your browser makes a lightweight request to our server, which performs the network lookup and returns the result. There is nothing to configure.
Is there a usage limit?
To keep the service free and within Cloudflare's free tier, we apply a reasonable daily request limit. For normal use you will not notice it.
