AS791

AS791 is a registered-but-dormant autonomous system held by American Information Network — publicly branded AiNET — a privately held Mid-Atlantic fiber network and data-center operator; as of 2026-07-31 it announces zero IPv4 and zero IPv6 prefixes in the global routing table, so live traffic does not currently transit this ASN.

The ASN was allocated 1990-12-13 per ARIN RDAP's top-level autnum registration event, with the record last changed 2025-09-08 (org handle AI, entity "AiNET Corporation," Beltsville, MD). The registrant name on the RIR record predates the operator's current public brand, AiNET, which markets itself as one of the Mid-Atlantic region's largest privately held fiber networks (10,000+ miles), plus the CyberNAP carrier-hotel data center and the ZSTOR cloud-storage division.

Routing data from RIPEstat and CAIDA agree AS791 is currently unrouted: 0 of roughly 328 RIS peers (v4) and 0 of 322 (v6) see it, CAIDA marks it not seen/not a clique member, and its customer cone is a singleton — itself, 0 prefixes, 0 addresses — with zero upstream, peer, or customer degree. CAIDA ranks it #79,459. Because no prefixes are announced, RPKI posture cannot be assessed; there are no live routes to validate against a ROA.

No public peering policy or ASN-specific technical page was found on AiNET's own site, and a PeeringDB lookup for ASN 791 did not resolve to a verifiable record (a same-numbered PeeringDB object turned out to be an unrelated network). Peering policy is therefore Unknown rather than assumed.

Network & routing

Network type

regional facilities-based fiber/ISP and data-center operator (Mid-Atlantic; 10,000+ miles of owned fiber, CyberNAP carrier hotel, ZSTOR cloud storage); not a pure transit carrier; no formal Tier 1/2/3 label published [Likely] — https://www.ai.net/fiber-network, https://www.ai.net/cybernap

Size

currently unrouted — 0 IPv4 prefixes / 0 addresses and 0 IPv6 prefixes; customer cone = 1 ASN (itself), 0 prefixes, 0 addresses [Confirmed] — RIPEstat routing-status / CAIDA AS Rank (2026-07-31/08-01)

Routing/peering

NOT announced — 0 of ~328 RIS peers (v4), 0 of 322 (v6) see it; CAIDA degree total 0 (customer 0, peer 0, provider 0); no upstreams, peers, or IX presence found. Peering policy Unknown — not published on ai.net; no resolvable PeeringDB record for ASN 791 [Confirmed for routing state; Unknown for peering policy]

RPKI

not assessable — no announced prefixes, so no live routes to validate against a ROA [Confirmed]

Notable usage

operator-stated (marketing-page) claims: 10,000+ miles of owned Mid-Atlantic/DC fiber; CyberNAP carrier hotel (~300,000 sq ft) with meet-me rooms; ZSTOR cloud storage; Global Cloud Connect (1Gb/s–400Gb/s); partner mentions include AWS, Azure, Google Cloud, Cloudflare — self-reported, not independently verified

Analyst note

AS791 is registered and administratively active under ARIN but has been dormant from a routing-announcement standpoint across all sources checked (RIPEstat, CAIDA, bgp.he.net, bgp.tools). WHOIS/RDAP resolves to American Information Network, publicly operating as AiNET, a Mid-Atlantic fiber and data-center company; no evidence links this specific ASN to abuse.
