Super detailed info for any domain name: registration status & dates, WHOIS, RDAP, DNS records, Name Servers, and more This extension started as a small project: see the expiry date of a domain. More functionality was added in time, and now the extension can show you everything about a domain name: WHO registered it, important dates (created or expiry), DNS Records, mentions in the news, WHOIS, RDAP, and more. Highlights: - Shows domain availability: registered, available or for sale - Show at which registrar the domain is registered - Important domain dates: registration date, expiry date - Registrant info (if public): person/company name, location, contact details - Info about Name Servers - DNS records: lists all subdomains - Domain history: timeline of domain changes in WHOIS, DNS or public sales - Does not track or record browser history. The only info used is the domain name in current tab when extension icon is clicked Change log: - v2.6 - Updated layout for History tab, added multiple DNS resolvers - v2.5 - Fixes for links to register domains - v2.4 - Load faster & more accurate domain info, using a mix of RDAP & WHOIS info - v2.3 - Discover more DNS records (subdomains) and wildcard (*) record - v2.2 - Show friendly message when WHOIS data can't be loaded - v2.1 - Load info about IPs on mouse hover in DNS Records tab - v2 - new UI, new & faster API
