Cogent Communications is tracked by Botcrawl as transit / backbone associated with AS174. The record includes representative routed prefix 38.0.0.0/8 for import validation and network identity matching.
Traffic from this network should be evaluated as infrastructure-origin traffic rather than automatically treated as a normal residential visitor. Combine ASN, CIDR, hostname, user-agent, request path, rate, geography, and rule outcomes before enforcement.
Log as transit/backbone. Do not block solely by ASN; only enforce against specific abusive downstream ranges or traffic patterns.
