AS283

AS283 is a low-numbered legacy autonomous system number registered under ARIN to MPower Labs, Inc., a privately held company in Austin, Texas. Despite its early two-digit-era ASN, the network operates today as a small single-homed enterprise stub: it announces just two IPv4 prefixes — 199.58.188.0/24 and 199.58.189.0/24, roughly 512 addresses — no IPv6, and receives transit from a single upstream, AS23005 (SWITCH, LTD). RIPEstat observes one routing neighbour and full v4 RIS visibility, confirming the prefixes are live and stably announced as of June 2026; CAIDA AS-rank and customer-cone figures were unavailable (the source timed out), so those remain unknown rather than zero. The ARIN contacts tie the network to the Rev Worldwide / MPOWER Ventures fintech group: the administrative, routing, and abuse roles resolve to Edy Ngamkhao at revworldwide.com, and MPower Labs was co-founded by the Sosa brothers, who also co-founded NetSpend. No notable public abuse signal was found across Spamhaus, AbuseIPDB, NANOG archives, MANRS, or general threat feeds as of 2026-06-25; Scamalytics rates the associated commercial brand 0/100 for fraud. Absence of signal here is consistent with the network's very small footprint rather than a deep clean-room audit. Both announced prefixes are IRR-valid; no RPKI ROA coverage is reported by bgp.he.net.

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal as of 2026-06-25 — not in Spamhaus ASN-DROP/SBL, AbuseIPDB, NANOG archives, or MANRS incident records; Scamalytics rates the related commercial brand 0/100 for fraud; absence reflects small footprint, not a deep threat-intel audit

Analyst note

Low ASN number is legacy-era but the network is a small modern enterprise stub; the autnum top-level registration date (2009-07-21) is the authoritative allocated_date — not the entity registration dates nested in entities[]. CAIDA rank/cone unknown due to source timeout.
