AS259

AS259 is a legacy three-digit autonomous system number registered under ARIN to the organization handle SCUBED, based in San Diego, California. Its ARIN RDAP autnum top-level registration event dates to 1989-01-04, placing it among the oldest ARIN-era ASN allocations, from the pioneering late-1980s era of inter-domain routing. Historical UUCP/ARPANET network maps from the mid-to-late 1980s associate the SCUBED brand with Systems Science & Software, Inc., an early San Diego research-and-engineering computing site running hosts such as scubed.arpa, s3ridge, and s3sun. The key triage point for AS259 is that it is effectively dormant today: every routing source consulted (RIPEstat, bgp.he.net, bgp.tools) agrees it announces zero IPv4 and zero IPv6 prefixes, has zero visible BGP peers, and zero observed neighbours. RIPEstat's routing-status shows the only historical BGP visibility on record is a brief six-day window in January 2003 (prefix 209.68.224.0/24, 2003-01-24 to 2003-01-29); the ASN has not been seen in global routing since. RPKI posture cannot be assessed because there are no active originations and therefore no ROAs. The ARIN POC (Stephen J. Schneider, handle SS135-ARIN) is flagged "Unvalidated POC — no response since 2017-11-16," and the SCUBED trademark (USPTO serial 78625725) was abandoned for failure to respond — both consistent with organizational dormancy. No notable public abuse signal was found as of June 2026: AS259 is absent from Spamhaus ASN-DROP, and no NANOG, AbuseIPDB, or threat-intelligence attributions were located — consistent with a clean, dormant ASN that originates no traffic.

Operator

SCUBED (ARIN org handle SCUBED-4); historical maps and a USPTO filing tie the SCUBED brand to Systems Science & Software, Inc. [Likely] — ARIN RDAP, trademark.trademarkia.com/scubed-78625725.html

Country / RIR

US, ARIN [Confirmed] — ARIN RDAP autnum; RIPEstat abuse-contact-finder (authoritative_rir: arin)

Allocated

1989-01-04 (ARIN registry date from autnum top-level registration event, NOT an IEEE date — IEEE publishes no ASN registration dates); last changed 1997-04-22 [Confirmed] — ARIN RDAP autnum top-level events

Org status

apparently defunct or dormant — ARIN POC unvalidated since 2017-11-16; SCUBED trademark (USPTO 78625725) abandoned; registrant address (3398 Carmel Mountain Road) now hosts an unrelated company (Solekai Systems) [Likely] — ARIN RDAP, trademark.trademarkia.com, yelp.com/biz/solekai-systems-san-diego

Contacts

POC Stephen J. Schneider (SS135-ARIN; unvalidated since 2017-11-16) — the POC's two personal mailboxes are withheld here, consult the ARIN RDAP record directly; registrant address 3398 Carmel Mountain Road, San Diego, CA 92121-1095, US

[Confirmed for RIR via RDAP/RIPEstat] — ARIN RDAP, RIPEstat abuse-contact-finder

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found as of 2026-06-20 — absent from Spamhaus ASN-DROP; no NANOG, AbuseIPDB, or threat-feed attributions located; the ASN originates no prefixes, so abuse traffic is operationally impossible in its current state

Network & routing

Network type

legacy/inactive ASN; historically a small private research/engineering network (UUCP/ARPANET-era San Diego site); no current PeeringDB record [Likely] — bgp.tools/as/259, historical UUCP maps

Size

dormant — 0 IPv4 prefixes / 0 IPv4 addresses and 0 IPv6 prefixes; observed_neighbours 0 [Confirmed] — RIPEstat routing-status / bgp.he.net / bgp.tools (2026-06)

Routing/peering

NOT announced — 0 RIS peers seeing it (0/327 v4, 0/324 v6); no upstreams, peers, or customer cone visible in any source [Confirmed]; no PeeringDB record / no published peering policy [Confirmed] — RIPEstat routing-status, peeringdb.com (404)

Routing history

only historical visibility on record is 2003-01-24 → 2003-01-29 (prefix 209.68.224.0/24); not seen in BGP since [Confirmed] — RIPEstat routing-status

RPKI

not assessable — AS259 announces no prefixes, so there are no ROAs to validate [Confirmed] — RIPEstat (rpki-validation skipped, no prefix)

Notable usage

registered 1989-01-04, one of the early ARIN-era ASNs; historical UUCP maps show SCUBED (Systems Science & Software, Inc.) operating hosts scubed.arpa (192.16.16.70, DEC MicroVAX II), s3ridge, s3sun [Likely] — groups.google.com/g/mod.map, bgp.tools/as/259

Analyst note

Encountered as a dormant legacy three-digit ASN registered to an early San Diego research entity; WHOIS resolves to SCUBED, no active routing, minimal community footprint. Clean, inactive ASN.
