Network Report
AS174 — Cogent Communications
What Predax has observed across this network's address space, and what it means for traffic screening.
About this network
Cogent Communications (AS174) is a consumer and business internet provider. The 441 addresses we have observed on it are the kind an ISP assigns to homes, offices and mobile devices — connections with a person behind them, not rented servers.
62 of those addresses (14%) carried a threat flag or a notable risk score when last checked. A small flagged share is normal for a large access network — individual subscribers get compromised, and some ISP ranges host small business servers — and it does not make the network itself suspect.

Observation window
Addresses on this network have been looked up through Predax between February 10, 2026 and August 30, 2026. Each figure on this page reflects an address's most recent check, not a permanent record.
Geographically, the observed addresses span 26 countries, with the largest share (359 of 441) geolocating to United States.
A footprint that wide usually means globally distributed infrastructure — the same operator announcing address space from many regions — rather than a network serving one local population.
Should you screen traffic from this network?
Traffic from this network is your audience, not your threat surface. Blocking an access network at this level turns away real people, and nothing in our observations justifies it.
If an individual address from this network is causing problems — failed logins, scraping, card testing — act on that address and that behaviour. Its report page shows what we know; the network-level numbers here are the context, not the verdict.
