About this ASN.

Updated  ·  Confidence: High  ·  6 sources  ·  How this page is checked

AS701 is the historic UUNET backbone, today operated by Verizon Business and registered under ARIN. It is one of the Internet's oldest large ASNs and carries a genuinely mixed role — a settlement-free backbone, business and residential access, and some mobile-data space — which is why route-intelligence tools tag it simultaneously as Tier-1, home ISP, business broadband, and mobile carrier. It originates roughly a thousand prefixes of its own and announces tens of thousands once customer space is included, with an originated IPv4 footprint around 40 million addresses; legacy UUNET/MCI space includes the 63.64.0.0/10 "UUNET63" block, a direct allocation to Verizon Business / MCI Communications Services whose registration still carries a UUnet Technologies technical contact. By topology it ranks among the top networks (community tools place it around #18 by AS cone and #10 by originated IPv4 space globally). Verizon runs regional siblings AS702 (EMEA) and AS703 (APAC), and keeps consumer mobile largely under AS6167 and AS22394 (Verizon Wireless), so much of Verizon's residential FiOS and wireless traffic lives outside AS701. For triage, AS701 most often appears as transit in an AS path, though it can also be business access; abuse on transit attaches to customers, while any eyeball/mobile space carries dynamic-reassignment and carrier-NAT caveats.

Security/abuse context

Network & routing

Network type
mixed — Tier-1 backbone + business/residential eyeball + some mobile [Confirmed] — bgp.tools tags + CAIDA
Size
~980–990 IPv4 prefixes originated (~5,355 total; ~21,091 announced incl. customers), ~38–411 IPv6; ~40.3M–41.9M IPv4 addresses; community ranks ~#18 AS cone / ~#10 originated IPv4 globally — BigDataCloud / bgp.he.net / bgp.tools (2026-05/06)
Routing/peering
~1,246 peers; upstreams effectively none at the Tier-1 level — bgp.he.net
Notable usage
historic UUNET global backbone, now Verizon Business; legacy UUNET/MCI space includes 63.64.0.0/10 "UUNET63" (direct allocation to MCI Communications Services / Verizon Business, RegDate 1999-01-22, originated by AS701; tech POC "UUnet Technologies, Inc.") — verizon.com/business
