User-Agent

CheckHost

User-agent strings are identity signals, not proof of identity. Confirm the source and behavior before trusting a request.

Verification and Detection

Verification method: Verify CheckHost by matching `CheckHost` to Check-Host.net evidence, then checking reverse DNS, source-network ownership, signed request data, or published crawler documentation when available.

CheckHost traffic is primarily detected by the `CheckHost` user-agent pattern. Compare source IPs, reverse DNS, request paths, and crawl cadence with Check-Host.net infrastructure before trusting the traffic.

Handling Guidance

Use this record as identity context. Verify the request source, behavior, and relevance to your site before allowing or restricting traffic.

CheckHost is used for uptime monitoring, synthetic checks, performance measurement, accessibility review, and site-health testing.
