AS188

AS188 is a low-numbered, early-registered Autonomous System Number held under ARIN by Science Applications International Corporation (SAIC), a Fortune 500 U.S. defense and government IT contractor headquartered at 12010 Sunset Hills Rd, Reston, VA. The ARIN RDAP record carries an AS-level registration event of 1988-05-09 and a last-changed event of 2025-05-27, with OrgId SAIC-59; status is active. In practice AS188 functions as a small stub/enterprise network for SAIC's own infrastructure rather than a transit provider — it has no IPv6, no recorded IX presence, and no downstream customers. The number of announced IPv4 prefixes is source-variable: RIPEstat, bgp.he.net, bgp.tools, and IPinfo consistently show 3 /24 prefixes (149.64.200.0/24, 198.22.15.0/24, 198.151.10.0/24 — 768 addresses, all RPKI-valid), while one aggregator (BGPView) reports a substantially larger ~39-prefix footprint; the live RIR-adjacent routing sources favour the 3-prefix view, so it is best described as a small network with a source-variable upper bound. The upstream/transit picture also differs by angle: RIPEstat/bgp.he.net/bgp.tools/IPinfo show transit exclusively via Amazon Web Services GovCloud (AS8987) — consistent with SAIC's 2023 AWS Strategic Collaboration Agreement and government-cloud orientation — whereas BGPView reports Cogent (AS174) and Zayo (AS6461). RPKI posture is strong (valid ROAs on the observed prefixes). No notable public abuse signal was found as of 2026-06-18; the one well-known SAIC security event (the 2011 TRICARE backup-tape theft) was physical-media loss, not an AS188 network/routing incident, and is not an abuse signal for this ASN.

Analyst note

Low-numbered legacy ASN whose WHOIS resolves to SAIC; functions as a small government-oriented stub network. Prefix count and upstream identity differ by source (3 prefixes / AWS GovCloud on RIR-adjacent live sources vs ~39 prefixes / Cogent+Zayo on BGPView) — reported as a range; no public peering page on saic.com (PeeringDB lists "Open" but is stale, last updated 2022, with no active IX/facility).
