Verizon

Verizon Business operates Autonomous System 701, one of the largest IP backbones in the world and a core network for the American telecommunications carrier. Registered in the United States, it provides enterprise internet, MPLS, and cloud connectivity services globally, alongside carrying traffic for Verizon's own operations. AS701 dates to the early commercial internet under its UUNET heritage and remains a widely used transit and access network. It is a frequent presence in the routing paths of enterprise and wholesale customers. Its address blocks span enterprise circuits and backbone links, reflecting Verizon's role as both an access carrier and a wholesale provider.
