Amazon Route 53 Health Checks

Listed only

Amazon Route 53 health checkers, which probe customer-configured endpoints from AWS data centers worldwide to drive DNS failover. AWS publishes checker source ranges only inside the general ip-ranges.amazonaws.com/ip-ranges.json feed (entries tagged ROUTE53_HEALTHCHECKS), a shape this directory's feed formats cannot consume, so no CIDR recipe is attached.
