Traffic and handling
- Traffic Classification
- CDN / Proxy Traffic
- Traffic Label
- CDN / Proxy
- 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 173.245.48.0/20. Match the ASN and representative CIDR, validate the proxy configuration, and apply behavior rules to the restored client IP rather than the shared edge address.
