Autonomous system detail

AS686

Not announced

Operated by OSD-GW-AS - 7th Communications Group/GNE.

Summary

// analyst note
Dormant/legacy ASN. ARIN autnum top-level registration event (1990-06-21) recorded as allocated_date per instructions, distinct from entity-nested 'last changed' events (1993, 2012) which were excluded as decoys. All routing sources (RIPEstat, CAIDA, bgp.he.net, bgp.tools) agree on zero announcements, zero peers, zero cone. No PeeringDB record; no operator-owned public site found (DoD-internal network, not a commercial operator).
// security note
NEUTRAL/DATED: no notable public abuse signal found as of 2026-07-18 across a Spamhaus ASN-DROP search, NANOG archives, and general threat-intel queries; the live ASN-DROP feed could not be directly diffed in this pass.

About this ASN.

Updated  ·  Confidence: Medium

AS686 (OSD-GW-AS) is a dormant legacy ASN registered under ARIN to the 7th Communications Group/GNE, a U.S. Department of Defense-affiliated entity with a registered Pentagon Room 1B471, Washington, DC address. Registry status is active, but the ASN is not currently visible anywhere in the global routing table.

ARIN's autnum record carries a top-level registration event dated 1990-06-21, with the record itself last changed 1991-01-10. The registrant organization, 7th Communications Group/GNE (ARIN org handle 7CG-3), was created the same day and last updated in ARIN's system on 2012-10-10 — administrative housekeeping, not a recent operational change.

Every routing source consulted agrees the ASN is unrouted. RIPEstat shows zero announced IPv4 and IPv6 prefixes, zero of 325 v4 and zero of 321 v6 RIS peers observing it, and zero observed neighbours. CAIDA's AS Rank places it at 79,459 with a customer cone of just itself — zero customers, zero peers, zero providers — and no PeeringDB record exists; a direct query for AS686 returns HTTP 404.

The registered address and organization name point to a Pentagon-based Office of the Secretary of Defense communications function, though no first-party document confirms the OSD/GW acronym expansion or ties the current registration to any specific present-day DISA or GDIT network contract. This reads as a DoD-internal network registration rather than a commercial operator with a public website or peering policy.

Network & routing

Network type
military/government gateway network, not a commercial transit or content network [Likely] — https://whois.arin.net/rest/org/7CG-3
Routing status
dormant — 0 IPv4/IPv6 prefixes announced, 0 RIS peers (0/325 v4, 0/321 v6), 0 observed neighbours [Confirmed] — RIPEstat routing-status; https://bgp.he.net/AS686; https://bgp.tools/as/686
Peering
no published policy; no PeeringDB record (peeringdb.com/asn/686 returns HTTP 404, checked directly) [Confirmed absence]
