You saw AS701 on an IP and want to know what it is. AS701 is one of Verizon's primary autonomous systems, a large US internet provider covering both consumer and business connections. This page explains what the ASN carries and how to treat it.
What is AS701?
AS701 is a main Autonomous System Number operated by Verizon (historically the UUNET / Verizon Business network). It is one of the oldest and largest ASNs in the ARIN region, so a route from AS701 belongs to Verizon's network. For the concept, see what an ASN is.
- ASN: AS701
- Operator: Verizon Business / Verizon
- Type: ISP (residential and business)
- Registry: ARIN (North America)
Who is Verizon?
Verizon is one of the largest telecom and internet providers in the United States, serving home broadband, business connectivity, and mobile customers. AS701 carries a mix of residential and business access traffic, so most of what you see from it is real end users and legitimate organizations.
Why AS701 traffic is mostly trusted
As an ISP network rather than a hosting one, AS701 carries genuine consumer and business connections, which score as higher trust than data-center traffic. A signup from AS701 is much more likely to be a real user than one from a cloud ASN.
Should you block AS701?
No. Blocking a major ISP would turn away real customers and businesses. Treat AS701 as trusted access traffic and rely on other signals for edge cases, since residential and business IPs can occasionally be abused via proxies.
