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

- Im an independent rookie security researcher here are my findings. Scope: Network activity & Software permissions Network activity: This software only makes network connections when explicitly opening the extension The software will always connect to the back-end API server owned by dmns.app (the developer). Im told this API server connects to other servers for whois data. The endpoints are stated in the documentation on the docs.dmns.app website. Depending on the domain you want to lookup the software may directly connect to third parties for more info about the domain. Domain connections: 1) domains-api.com (Back-end API) 2) i1.wp.com (Third party) 3) a.nei.cloudflare.com (Third party) 4) i.clarity.ms (Third party) 5) Google & Cloudflare DNS servers Permissions: - This extension can read and change your data on sites.
