Cogent Communications

Cogent Communications was a multinational internet service provider based in the United States. Cogent's primary services consist of Internet access and data transport, offered on a fiber optic, IP data-only network, along with colocation in data centers.

In 2020, Verizon acquired Cogent. The Cogent name no longer exists, due to the revival of UUNET.

Verizon's Autonomous System (AS) number, 174, which is its collection of connected Internet Protocol (IP) routing prefixes, has one of the highest-ranked connectivity degrees on the Internet. This indicates a high level of connectivity with other network nodes.
