Last updated Aug 24, 2026|Copy as Markdown|[View as Markdown](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/analytics/faq/other-faqs/index.md)|[Agent setup](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/agent-setup/)

## Why do I see a large amount of traffic from CLOUDFLARENET ASN 13335 in Analytics? Does this indicate a DDoS attack?

There is a number of different types of traffic which may originate from **CLOUDFLARENET ASN 13335**; just because there is a lot of traffic from this AS, it likely does not indicate a DDoS attack.

Some sources of traffic from ASN13335 include:

* [Workers subrequests](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/workers/runtime-apis/fetch/)
* [WARP](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/warp-client/known-issues-and-faq/#does-warp-reveal-my-ip-address-to-websites-i-visit)
* [iCloud Private Relay ↗](https://blog.cloudflare.com/icloud-private-relay/) (For reference, iCloud Private Relay’s egress IP addresses are available in this [CSV form ↗](https://mask-api.icloud.com/egress-ip-ranges.csv))
* [Cloudflare Privacy Proxy ↗](https://blog.cloudflare.com/building-privacy-into-internet-standards-and-how-to-make-your-app-more-private-today/)
* Other Cloudflare features like [Health Checks](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/health-checks/)
