Domain Details and Reverse Lookups

Every domain in Domain Search has a full record: registration (WHOIS) with its history, DNS with its history, the certificate, website data, facts about the name itself, and lists of related domains. You can read it in a drawer next to your results, or open it in a page tab of its own.

Before You Start

  • Package: Deep Search & Insights (DSI), with Domain Search and domain details included.
  • Role: Admin or Member.

Where to Find It

Sidebar: DEEP SEARCH & INSIGHTS › DOMAIN SEARCH, then a result · https://platform.deepinfo.com/app/dsi/domain-search

  • Drawer: select a row in the Domain Search results.
  • Page tab: select OPEN IN NEW TAB at the top of the drawer, or type a domain name in the search box and pick OPEN IN NEW TAB from the suggestions. The tab is named after the domain.

Find Domains That Share a Detail (Reverse Lookups)

Some values in the record, such as a name server, are clickable. Hover over one: a tooltip asks whether you would like to see what other domains are owned by it, with SEE OTHERS. Select SEE OTHERS to list the domains that share that IP address, name server, mail server or registrant e-mail.

Good to Know

  • EXPORT AS JSON at the top of the page tab does not download anything. To get a domain's record as data, use Domain Detail in the API.
  • The external-link icon opens the domain itself in your browser.
