Run Instant Lookups

Instant Lookup queries one target in real time: its registration (Whois), DNS records, certificate (SSL), website data, technologies, a screenshot, or a port scan. Use it when you need the current answer for a single domain or IP address, rather than a search across Deepinfo's data.

Before You Start

  • Package: each lookup type is part of your package separately. A type that is not included says so in its tab.
  • Role: Admin or Member.

Where to Find It

Sidebar: DEEP SEARCH & INSIGHTS › INSTANT LOOKUP · https://platform.deepinfo.com/app/dsi/instant-lookup

The breadcrumb reads DSI / INSTANT LOOKUP. Each lookup runs in a page tab named after its type, for example Whois Lookup; see Page tabs.

The Lookup Types

Pick a type with the + button above the page (it opens a new tab) or with the type switcher at the start of the input (it changes the current tab).

Type What to enter Advanced options
Whois Lookup A domain name or an IP address None
DNS Lookup A domain name or subdomain The DNS record types to query
SSL Lookup A domain name or an IP address PORT and PROXY
Webdata Lookup A domain name or a URL PROXY
Technology Lookup A domain name or an IP address None
Screenshot Lookup A domain name or an IP address Page, image and browser options
Port Scanner Lookup A domain name or an IP address Scan mode and ports

The + menu with the lookup types.

Run a Lookup

  1. Choose the lookup type.
  2. Type the target in the input.
  3. Optional: select SHOW ADVANCED OPTIONS and set the options (see below).
  4. Select LOOKUP.

Some lookups take a while; a Whois lookup can take close to a minute. The button shows a spinner meanwhile. After a result, LOOKUP stays unavailable until you change the input.

Warning

When you switch the lookup type, the input is filled again with the last target you looked up, even if you had cleared it. Check the target before you select LOOKUP. Run Port Scanner Lookup only against hosts you own or are allowed to scan.

Advanced Options

  • DNS Lookup (PARAMETERS): tick the DNS Types to query. You can select up to 5 types per request. SELECT DEFAULT ONES picks A, TXT, MX, NS and CNAME; UNSELECT ALL clears the list.
  • SSL Lookup (PARAMETERS): PORT (443 unless you set another) and PROXY (the address of a proxy to connect through). CLEAR PARAMETERS empties both.
  • Port Scanner Lookup: Light Mode or Full Mode, and PORTS: TCP & UDP Ports, TCP Ports, UDP Ports or Custom Ports.
  • Screenshot Lookup:
    • checkboxes such as Full page screenshot, Lazy loading, Block Ads, No cookie banners, Disable Javascript, Retina, Mobile, Landscape and Touchscreen;
    • Export Image Options: DOCUMENT TYPE, IMAGE QUALITY and THUMBNAIL;
    • Browser Options: BROWSER SIZE WIDTH, BROWSER SIZE HEIGHT, SCALE, DELAY, TIMEOUT and more;
    • SEE ALL adds HTML Options, such as the element to capture, headers, cookies, the user agent, a proxy, injected CSS and a location; HIDE folds them away.

Read the Result

A Whois lookup result in the parsed view, with RAW, CHECK HISTORICAL WHOIS RECORDS and EXPORT in the result header.

The result header shows the target, the kind of record (for example Whois Record), and:

  • RAW and PARSED: switch between the raw data and a readable layout.
  • CHECK HISTORICAL WHOIS RECORDS (Whois) or CHECK HISTORICAL DNS RECORDS (DNS): open a drawer with the stored history, for example Historical Whois Records with the number of records found and their dates. SSL results have no history button.
  • EXPORT: save the result as a file.

What each result contains:

Type Result
Whois Lookup The registration dates, name servers, status and registrar, and the Registrant block
DNS Lookup One table per record type, for example A Records, MX Records (with PRIORITY), NS Records and TXT Records. A type with no record shows No Result Found.
SSL Lookup Details (including the SAN LIST), Fingerprint (including the PUBLIC KEY), Signature (including VALID) and Extensions

Good to Know

  • An instant lookup asks for the current data at the moment you run it. Domain Search and the domain details show the data Deepinfo has already collected; see Search domains.
  • Your lookup tabs and the last result are kept in this browser for your user, so they are still there after a reload. Close a tab to remove it.
