Domain Intelligence Setup

Learn how to enable and configure Domain Intelligence for your monitoring checks.

Prerequisites

An active Nano plan subscription
At least one monitoring check with a domain-based URL

Enabling Domain Intelligence

Per-Check Setup

Navigate to the check you want to enable Domain Intelligence for
Open the check settings
Toggle Domain Intelligence to enabled
Save the check

The domain will be automatically extracted from the check URL and monitoring will begin.

Automatic Domain Extraction

exit1.dev automatically extracts the base domain from your check URL:

Check URL	Extracted Domain
`https://www.example.com/health`	`example.com`
`https://api.example.com/v1/status`	`example.com`
`https://app.example.co.uk`	`example.co.uk`

Domain Information

Once enabled, exit1.dev retrieves and displays:

Registrar - The domain registrar
Registration date - When the domain was first registered
Expiration date - When the domain registration expires
Last updated - When the registration was last modified
Status codes - Domain status flags (e.g., clientTransferProhibited)

RDAP Protocol

exit1.dev uses the Registration Data Access Protocol (RDAP) to query domain information. RDAP is the modern replacement for WHOIS, offering:

Standardized JSON responses
Better internationalization support
Access control and authentication capabilities
Referral support across registries

Troubleshooting

Domain not found

If Domain Intelligence shows “domain not found,” the TLD may not support RDAP. Check the IANA RDAP Bootstrap file for supported TLDs.

Stale data

Domain registration data is cached and refreshed periodically. If you’ve recently renewed a domain, it may take some time for the updated expiration date to appear.
