About this ASN.

Updated  ·  Confidence: High  ·  4 sources  ·  How this page is checked

AS7018 is AT&T's flagship US autonomous system, registered under ARIN since July 1996 and now held by AT&T Enterprises, LLC (the legal entity was renamed from AT&T Services Inc. in late 2024). It is a genuinely mixed network: it serves tens of millions of US residential and business access customers while also operating as a settlement-free Tier-1 backbone. In CAIDA AS Rank it sits at #31 globally, with a customer cone of roughly 2,693 ASNs, ~83,701 prefixes, and ~462 million addresses, and an AS degree near 2,323 (about 2,290 customers, 33 peers, and zero providers — transit-free). Its IPv4 footprint is among the largest anywhere, including the legacy 12.0.0.0/8 block, totaling on the order of 89 million addresses. AT&T runs regional siblings for other continents — AS2685 (Canada), AS2686 (EMEA), AS2687 (APAC), AS2688 (LATAM) — plus the largely-consolidated US peering ASN AS7132 and the legacy BellSouth AS6389. For triage, an AS7018 address may be a residential/business subscriber (consumer ranges such as 12.x, 99.x, 172.x with dynamic reassignment) or part of the transit backbone, so disambiguate by prefix; on backbone space, abuse attaches to downstream customers.

Security/abuse context

mixed eyeball + backbone. Consumer ranges (12.x, 99.x, 172.x) are access with dynamic reassignment; on backbone/transit, abuse attaches to downstream customers. Standard residential dynamic-IP caveat applies. No carrier-specific abuse listing of note as of 2026-06-04

Network & routing

Our research recorded 8,083 IPv4 prefixes; RouteViews currently observes 629.
Network type

Size
CAIDA AS Rank #31 globally — customer cone ~2,693 ASNs / ~83,701 prefixes / ~461,814,278 addresses; AS degree ~2,323 (~2,290 customers, ~33 peers, 0 providers); ~8,083 IPv4 prefixes total (~89.26M addrs, incl. legacy 12.0.0.0/8), ~207 IPv6 — asrank.caida.org/asns/7018, BigDataCloud (2026-05/06)
Routing/peering

Analyst note
Could be a US residential/business subscriber OR a transit path — disambiguate by prefix (consumer ranges vs. infrastructure). As a Tier-1 backbone it frequently appears mid-path.
