Search Domains

Domain Search queries Deepinfo's data on domains and subdomains across the internet. Search by name, or combine filters on registration (WHOIS), DNS, certificates (SSL), website data and name properties. Each result opens a full record of the domain.

Before You Start

  • Package: Deep Search & Insights (DSI), with Domain Search included. Without it, the page shows a notice that it is not included in your package.
  • Role: Admin or Member.

Where to Find It

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

The breadcrumb reads DSI / DOMAIN SEARCH. The page uses page tabs; see Page tabs.

Read the Screen

Domain Search before the first search, numbered 1 to 4.

  1. Page tabs: the first tab is Domain Search.
  2. Search box (Search domain...) with the tabs FILTERS and SAVED SEARCH. Saving searches is not available, so SAVED SEARCH has no effect.
  3. Filter groups: DOMAIN TYPE, WHOIS, DNS, SSL, WEBDATA, DOMAIN NAME, EXTENSION and SUBDOMAIN, then HIDE FILTERS and SEARCH.
  4. Before your first search, a Did you know? panel shows a fact about domains.

Search by Typing

  1. Type a domain name, for example acme.example, in the search box.
  2. A list of suggestions opens. For a domain name they are:
    • OPEN IN NEW TAB: open the domain's record in a new page tab (see Domain details).
    • EXACT DOMAIN: search for this name.
    • SPLIT INTO PARTS: search the name and the extension separately.
    • OTHER EXTENSIONS: the same name under other extensions.
    • ALL SUBDOMAINS: the domain's subdomains.
    • LOOKALIKES: names that look like this one.
    • USES THIS NAMESERVER and USES THIS MAIL SERVER: domains that share its name server or mail server.
  3. Pick one with the mouse, or move through the list with the keyboard; the hints at the bottom of the list show the keys (NAVIGATE, ADD TO FILTERS, REPLACE FILTERS, BACK).

Other input, such as an e-mail address, an IP address, a URL or a plain keyword, gets its own suggestions.

Picking EXACT DOMAIN opens a new page tab and runs the search at once. Its results can include the domain's subdomains; to keep only domains, add a DOMAIN TYPE filter.

The suggestion list for a typed domain name, from OPEN IN NEW TAB to USES THIS MAIL SERVER, with the keyboard hints.

Search With Filters

  1. Select a filter group, for example WHOIS, and pick a field.
  2. Choose the rule (MUST, MUST NOT or SHOULD), the operator and the value.
  3. Add more rules if you need them, then select SEARCH.

The FILTERS APPLIED bar shows each rule with its type, group, field, operator and value, for example MUST Domain Name → Domain Name EQUAL 'acme.example'. CLEAR FILTERS removes them all.

Group Examples of fields
DOMAIN TYPE Domains only or subdomains only
WHOIS Create, expiry and update dates; registrant details; registrar; name servers; privacy
DNS A, AAAA, CNAME, MX, NS, SOA and TXT records; IP history
SSL Validity dates, fingerprints, subject and issuer, self-signed and valid flags
WEBDATA HTTP status codes, redirection, final URL, headers, cookies
DOMAIN NAME Name, length, keywords, language, and whether it contains numbers, hyphens or confusable characters
EXTENSION Extension, type (gTLD or ccTLD), IDN
SUBDOMAIN Subdomain name, length and level

See Search, filter and export lists for how rules combine.
