What is nask?
Nask is a specialized automated agent designed to perform targeted connectivity and health checks across web infrastructure. It operates as a verified utility, primarily utilized by its parent organization to ensure that services remain reachable and responsive. Unlike general-purpose crawlers, it does not index content for search or data mining purposes, focusing instead on maintaining operational uptime and system integrity.
Identification
Why it crawls your site
The bot crawls to verify that specific endpoints are correctly configured and responding within expected latency parameters. By systematically pinging services, it allows administrators to detect outages or misconfigurations in real-time. Operators can verify the legitimacy of this traffic by checking the source IP against the official Nask infrastructure registry or by observing the specific, non-intrusive request patterns associated with its signature.
IP ranges
Requests from nask originate from these published ranges. For strict verification, match the source IP against this list in addition to checking the user-agent and reverse-DNS.
Block or allow nask
Add a Disallow rule for nask in your robots.txt file. You can also block at the server level using your web server configuration or CDN firewall rules to filter requests matching the user-agent string.
# Block nask from crawling your entire site User-agent: nask Disallow: / # Allow nask full access User-agent: nask Allow: /
Ensure your robots.txt allows nask. Verify requests by checking the user-agent string.
