AS706

AS706 is an active legacy ASN registered under ARIN to IBM's Advanced Workstations Division in 1990, and today it routes as a small downstream network with Kyndryl (AS16807) as its sole observed upstream and peer — not an IBM-operated backbone in its own right.

The registrant name (AWDIC — Advanced Workstations Division, IBM Corporation) has never been updated at ARIN despite the division and IBM's broader managed-infrastructure business having been spun off into Kyndryl in 2021. That 2021 spin-off likely explains why Kyndryl, not IBM, now appears as the ASN's operational upstream. The ARIN registration event dates to 1990-08-20, with a separate "last changed" event on 2000-08-31; a primary ARIN point of contact (Mark Howard, MH486-ARIN) carries an unvalidated-POC flag with no confirmed response since 2010-06-16.

Live routing data shows a small, stable footprint: two independent sources (bgp.tools-derived and bgpview.io/db-ip.com summaries) agree on 7 announced IPv4 /24 prefixes (roughly 1,792 addresses) and zero IPv6 prefixes, with a single upstream/peer relationship to AS16807. A third source's prefix count (~16) was internally self-contradictory in its own summary and is treated as lower-confidence. CAIDA AS Rank places AS706 at rank 29561 (seen; clique member), with a customer cone of 1 ASN / 7 prefixes / 1,792 addresses; RPKI/ROA status could not be sourced for AS706 in this pass.

No dedicated operator web page, peering-policy document, or investor-relations page names AS706 specifically — neither ibm.com nor kyndryl.com documents this ASN, so website and peering_policy are recorded as sourced Unknowns rather than inferred.

Country / RIR

US, ARIN [Confirmed] — https://rdap.arin.net/registry/autnum/706

Allocated

1990-08-20 (ARIN RDAP autnum top-level registration event); last changed 2000-08-31 [Confirmed] — https://rdap.arin.net/registry/autnum/706

Org status

registrant "Advanced Workstations Division, IBM Corporation" is a historical internal IBM division name carried unchanged at ARIN since 1990; primary POC (Mark Howard, MH486-ARIN) flagged unvalidated since 2010-06-16 [Likely] — https://rdap.arin.net/registry/autnum/706

Contacts

no dedicated abuse/NOC contact found beyond the ARIN RDAP POC record (MH486-ARIN, unvalidated); org address 11400 Burnet Road, Austin, TX 78758; technical/abuse POC address on file at Research Triangle Park, NC [Likely] — https://rdap.arin.net/registry/autnum/706

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found as of 2026-07-25 — CleanTalk shows 0.00% spam rate; Spamhaus ASN-DROP could not be queried directly (DNS failure) so is unverified rather than confirmed clean; no NANOG/Talos hijack reporting found

Network & routing

Network type

legacy enterprise/end-user ASN, currently a small downstream network routed via Kyndryl (AS16807); not a transit or content-network operator [Likely] — https://bgp.tools/as/706

Size

7 IPv4 prefixes (~1,792 addresses), 0 IPv6 prefixes [Confirmed, two sources] — https://bgpview.io/asn/706, https://db-ip.com/as706-advanced-workstations-division-ibm-corporation

Routing/peering

single upstream/peer AS16807 (Kyndryl); no other peers observed; CAIDA AS Rank 29561 (seen; clique member); customer cone 1 ASN / 7 prefixes / 1,792 addresses; CAIDA asnDegree total 1 (provider 1, customer 0, peer 0); RPKI/ROA status Unknown (not present in any queried source) [Likely for upstream; Confirmed for rank/cone (CAIDA); Unknown for RPKI] — https://bgpview.io/asn/706, https://asrank.caida.org/asns/706

RPKI

Unknown — RPKI-validation lookup was not performed against a specific prefix in this pass; no ROA status available [Unknown]

Notable usage

legacy internal IBM ASN registered to the Advanced Workstations Division (RS/6000-era engineering group); registrant name unchanged since 1990 despite IBM's 2021 spin-off of managed infrastructure into Kyndryl, which now appears as AS706's operational upstream

Analyst note

Small, low-profile legacy IBM ASN whose ARIN registration name was never updated after the 2021 IBM/Kyndryl split; live routing confirms Kyndryl now carries it operationally. No dedicated operator web presence exists to cite for website or peering policy.
