Short answer

How can I track historical DNS changes with my AI?

Your AI uses SecurityTrails to pull old DNS records and WHOIS data. This lets you see how a domain's infrastructure or ownership has changed over time. You get a full breakdown of past configurations and registration history.

Where every insight lands.

Mapping domain evolution

The AI processes raw historical data into clear intelligence for your investigation.

INFRASTRUCTURE

Legacy IP maps

The AI identifies old A, AAAA, and MX records. You see exactly which servers hosted the domain in the past.

OWNERSHIP

WHOIS shifts

The AI tracks changes in registrants and contact info. You catch when a domain moves between different entities.

SECURITY

Attack surface

The AI finds forgotten subdomains or old records. You use this to find hidden entry points in old setups.

HUMAN

Final verification

The AI presents the timeline, but you decide if the patterns indicate a takeover or a simple migration.

The workflow

What your AI does when the request arrives.

The AI acts as a researcher, pulling deep history that isn't visible on a standard lookup.

  1. Fetch DNS history

    The AI pulls every historical DNS record associated with the target domain.

    get_dns_history

  2. Retrieve WHOIS data

    The AI looks up previous registration details and ownership records.

    get_whois_history

  3. Analyze changes

    The AI compares the new records against the old ones to find specific shifts.

    get_dns_historyget_whois_history

  4. Summarize findings

    The AI organizes the timeline of changes into a readable report for you.

FAQ

How this task behaves.

  • 01

    Can the AI change my DNS records?

    No. The AI can only read historical data. It cannot modify any live DNS settings or WHOIS information.

  • 02

    Does the AI store my SecurityTrails login?

    No. Your credentials are encrypted and managed by Vinkius so your AI client can use them securely.

  • 03

    Can I use this to find current WHOIS data?

    No. This specific task is designed to pull historical records through get_whois_history.

  • 04

    Will the AI automatically alert me to changes?

    No. The AI only performs analysis when you specifically ask it to via a prompt.

  • 05

    Can the AI perform a real-time DNS lookup?

    No. This connector focuses on historical data through get_dns_history rather than live, real-time queries.
