One click reveals DNS records and domain registration data for the website you're currently on.
Whois / DNS Peek is a small diagnostic utility for anyone who needs to inspect a domain quickly — developers debugging DNS, sysadmins checking propagation, or anyone curious about a site they've landed on.
Click the toolbar icon and the popup shows:
- DNS records — A, AAAA, CNAME, MX, NS, TXT — for the current tab's hostname, resolved over DNS-over-HTTPS
- Registration data — registrar, creation date, last updated, expiration, status flags, and authoritative nameservers — via RDAP, the modern replacement for legacy whois
- Reverse lookup (PTR) when the active tab is an IP address
Inspect the latest comments and rating distribution.
