Overview
KPN operates a transit or backbone network associated with AS1136.
This record includes the representative IPv4 CIDR 31.149.0.0/16. It is not an exhaustive list of the network’s address space or current routing announcements.
This is a network-origin record, not an exact physical-facility location or proof that a request is automated. Evaluate the ASN and CIDR together with the User-Agent, request path, request rate, session behavior, and application context before enforcement.

Traffic and handling

- Risk Level
- Low
- Recommended Action
- Use for routing context only. Do not block a transit ASN or representative backbone range as though it identifies the originating customer.
- Default Rule Action
- Log
- Common Pattern
- Transit and backbone ranges provide routing context and may carry traffic for many unrelated downstream networks.
- Detection Notes
- Match AS1136 and representative CIDR 31.149.0.0/16, then confirm the actual origin network, request identity, and behavior before enforcement.
