- Risk Level
- Low
- Recommended Action
- Log by default. Do not block the provider range wholesale. Restore and validate the trusted client IP before applying visitor-level rules.
- Default Rule Action
- Log
- Common Pattern
- Shared edge addresses can represent many unrelated visitors, proxied applications, cached requests, and security-filtered traffic.
- Detection Notes
- Match AS13335 and representative CIDR 173.245.49.0/24, then validate the service configuration and apply visitor-level rules to the restored or verified client identity before enforcement.
