AS891

AS891 is a currently dormant ASN registered to Profound (legal name Cooper Square Technologies Inc.), an AI Answer Engine Optimization (AEO) brand-visibility marketing SaaS platform — not a traditional ISP, transit, or content network. As of an August 2026 check it announces zero IPv4 and zero IPv6 prefixes, so it carries no live routing footprint to assess.

ARIN RDAP's autnum record shows a top-level registration/last-changed event of 2026-07-20 for the current registrant (org handle CST-128, "Profound"). This is a first-party registry date and is recorded as this entry's allocated_date, but it most likely marks a registrant change rather than the AS number's original-ever allocation: two third-party aggregators (db-ip.com, ipgeolocation.io) still cache an earlier registrant, "SB-AS-001 — Smart Bid Inc," with a 2022-06-07 date, and RIPEstat/CAIDA still surface that same stale holder label.

Routing sources agree unanimously that AS891 is not in the global table: RIPEstat shows 0 RIS peers seeing it (0/327 v4, 0/321 v6), CAIDA's AS-relationship degree count is 0 across customer/peer/provider, and bgp.he.net and bgp.tools both show 0 announced prefixes and 0 observed BGP peers. No PeeringDB network record exists for AS891. CAIDA's customer cone is a singleton (the ASN itself, 0 prefixes, 0 addresses), and its CAIDA AS rank of 79,459 sits near the bottom of the global ranking.

Profound the company is independently notable — founded 2024, reported to have raised roughly $58.5M including a 2025 Series B, and reported to have signed a 2026 office lease in New York — but that is company-level notability, not evidence of traffic on AS891 itself.

RPKI posture cannot be assessed: with zero announced prefixes there are no ROAs to validate against, and bgp.tools independently reports no valid or invalid RPKI-originated prefixes recorded for the ASN.

Allocated

2026-07-20 (ARIN RDAP autnum top-level registration event; last-changed event carries the identical timestamp) — reflects the current registrant's registration event, not necessarily the AS number's original allocation, given a stale prior-registrant label ("SB-AS-001 — Smart Bid Inc," cached date 2022-06-07) still surfaced by third-party aggregators [Confirmed for the 2026-07-20 event; Likely for the registrant-change interpretation] — https://rdap.arin.net/registry/autnum/891, https://bgp.tools/as/891, https://db-ip.com/as891-smart-bid-inc

Org status

ARIN RDAP status "active" for AS891; registrant org CST-128 ("Profound"), registered address 1 Union Square West, FL2, New York, NY 10003 [Confirmed] — https://rdap.arin.net/registry/autnum/891

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found as of an August 2026 search — not in NANOG mailing-list archives, and general Spamhaus/AbuseIPDB/URLhaus web searches surfaced no AS891-specific listings; dedicated Spamhaus DROP/EDROP and abuse.ch ASN-report pages were not directly queried, so this is a partial negative rather than a confirmed-clean record

Network & routing

Network type

not an ISP/network operator — Profound is a marketing/analytics SaaS company; AS891 shows zero originated prefixes and zero observed BGP peers, i.e. it is not currently used to route any network

[Confirmed] — https://www.tryprofound.com, https://bgp.he.net/AS891, https://www.peeringdb.com/api/net?asn=891

Size

dormant — 0 IPv4 prefixes / 0 IPv4 addresses, 0 IPv6 prefixes; CAIDA customer cone = 1 ASN (itself), 0 prefixes, 0 addresses; CAIDA AS rank 79,459 [Confirmed] — RIPEstat routing-status / CAIDA ASRank / bgp.he.net / bgp.tools (2026-08)

Routing/peering

NOT announced — 0 RIS peers seeing it (0/327 v4, 0/321 v6); CAIDA degree total 0 (customer 0, peer 0, provider 0); no upstreams or peers visible in any source; no PeeringDB network record exists for AS891 [Confirmed] — https://stat.ripe.net/data/routing-status/data.json?resource=891, https://bgp.tools/as/891, https://www.peeringdb.com/api/net?asn=891

RPKI

not assessable — AS891 announces no prefixes, so there are no ROAs to validate; bgp.tools shows no valid or invalid RPKI-originated prefixes recorded [Confirmed] — https://bgp.tools/as/891

Notable usage

none observed for AS891 itself (dormant). The registrant organization, Profound, is a notable AI-search-visibility startup (founded 2024, reported ~$58.5M raised including a 2025 Series B, and a 2026 NYC office lease per secondary business press) — company-level notability, not ASN traffic evidence

Analyst note

AS891 is registered to Profound, an AI Answer Engine Optimization SaaS company, not an ISP; as of an August 2026 check it announces nothing and has no PeeringDB record, so no peering-policy or traffic claim can be made. Third-party aggregators (RIPEstat, CAIDA, db-ip.com, ipgeolocation.io) still cache a prior registrant label, "SB-AS-001 — Smart Bid Inc," which conflicts with the current ARIN RDAP record and both independent BGP lookers (bgp.he.net, bgp.tools), which already agree on Profound; this reads as aggregator cache lag behind a recent registrant change, not two coexisting registrations — Unknown/Likely mix, treat live RDAP as authoritative.
