ASN summary
How to read the scale of AS174
COGENT-174 - Cogent Communications, LLC currently reports 4597 prefixes and 80 upstream, downstream, or peer relationships. These counts describe the current dataset; they do not by themselves prove network quality, reach, or service use.
What can an ASN page answer?
An ASN page shows the public organization label, country or region, BGP prefixes, and available peer and upstream relationships. It adds network context but cannot confirm a website host, physical facility, security status, or service quality.
How should you read the organization and region fields?
COGENT-174 - Cogent Communications, LLC is currently associated with an unknown region. These values come from public network sources and are useful lookup clues; an organization label, registration region, and actual service location may differ.
How should you verify the AS174 result?
The page shows ASN data returned by the current upstream query; interpret it with the update time. Open representative IP pages from the same network and compare prefixes, source labels, and query times. Verify operator or service claims with the relevant registry or network operator.

Frequently asked questions about this ASN page
What does AS174 represent?
AS174 is an autonomous system number. The current source associates it with COGENT-174 - Cogent Communications, LLC and the region field an unknown region; those values add network context but do not prove a specific service, physical location, or quality level.
What are peers, upstreams, and prefixes useful for on the AS174 page?
They help explain the scale, interconnection depth, and route structure of AS174. Richer peering and upstream data often indicate broader network reach, but they should still be interpreted together with prefixes and related IP landing pages.
What should you do after reviewing AS174?
Open a concrete IP page to check how the address maps into AS174, then compare the prefix, source labels, and query time. Verify operator or service claims with the relevant registry or network operator.
