Overview
GTT Communications is tracked by Botcrawl as a transit or backbone network associated with AS3257.
This record includes the representative IPv4 range 89.149.128.0/18. It is not an exhaustive list of the Network’s announced prefixes.
This is a network-origin record, not an exact physical-facility location or proof of automation. Use ASN and CIDR identity together with User-Agent, request path, rate, session behavior, and application context before enforcement.

Traffic and handling
- Traffic Classification

- Transit / Carrier
- 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 AS3257 and representative CIDR 89.149.128.0/18. Treat the ASN and CIDR as network context. Confirm the actual origin network, request identity, and behavior before enforcement.
