AS707

AS707 is a dormant U.S. Air Force autonomous system, registered under ARIN as ELAN-AS to Air Force Systems Networking, that currently announces zero IPv4 and zero IPv6 prefixes and shows no active BGP peers, upstreams, or customers on the public routing table.

ARIN RDAP's top-level autnum registration event puts the ASN's allocation at 1990-08-20, with a last-changed date of 2008-08-18. The registrant is org handle 7ESG, address 501 East Moore Dr., Bldg 884 Rm 1100, Gunter Annex, Maxwell AFB, AL 36114, US. Administrative/registration point of contact routes to DISA-Columbus rather than a dedicated abuse desk.

Routing visibility is consistent across sources: bgp.he.net and bgp.tools both show 0 announced IPv4/IPv6 prefixes and 0 observed peers, RIPEstat/CAIDA data shows 0 of 328 RIS peers (v4) and 0 of 324 (v6) seeing any announcement, a CAIDA AS rank of 79,459, and an empty customer cone (1 ASN, 0 prefixes, 0 addresses) with AS degree 0 in every direction. There is no PeeringDB profile for AS707 (peeringdb.com/asn/707 returns 404) and no discoverable public operator website or peering-policy page — consistent with a closed, non-publicly-routed DoD administrative network rather than a commercial operator.

RPKI posture cannot be assessed: AS707 announces no prefixes, so no ROAs exist to validate against it.

Operator

Air Force Systems Networking (ARIN org handle 7ESG, U.S. Air Force / DoD administrative network) [Confirmed] — ARIN RDAP autnum/org (https://rdap.arin.net/registry/autnum/707, https://whois.arin.net/rest/org/7ESG)

Country / RIR

US, ARIN [Confirmed] — ARIN RDAP

Allocated

1990-08-20 (ARIN RDAP autnum top-level registration event); last changed 2008-08-18 [Confirmed] — https://rdap.arin.net/registry/autnum/707, corroborated by https://bgp.tools/as/707

Org status

active per ARIN RDAP autnum status [Confirmed] — https://rdap.arin.net/registry/autnum/707

Contacts

DISA-Columbus registration mailbox (disa.columbus.ns.mbx.arin-registrations@mail.mil); registered address 501 East Moore Dr., Bldg 884 Rm 1100, Gunter Annex, Maxwell AFB, AL 36114 [Confirmed] — ARIN RDAP entity REGIS10-ARIN

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found as of 2026-07-25 — not in Spamhaus ASN-DROP JSON feed, NANOG archives, or general web search; distinct from the unrelated 1997 "AS7007 incident"

Network & routing

Network type

U.S. federal government / Department of Defense (Air Force) internal network, not a commercial ISP or transit provider [Confirmed] — ARIN RDAP, ARIN org record

Size

dormant — 0 IPv4 prefixes / 0 IPv4 addresses and 0 IPv6 prefixes; customer cone = 1 ASN (itself), 0 prefixes, 0 addresses; AS degree 0/0/0 [Confirmed] — bgp.he.net, bgp.tools, CAIDA AS Rank (2026-07)

Routing/peering

NOT announced — 0 of 328 RIS peers (v4), 0 of 324 (v6) see it; no upstreams or peers visible in any source; no PeeringDB profile (peeringdb.com/asn/707 = 404, verified live) [Confirmed]

RPKI

not assessable — AS707 announces no prefixes, so there are no ROAs to validate [Confirmed] — bgp.he.net

Notable usage

registrant address (Gunter Annex, Maxwell AFB, AL) is geographically co-located with Air Force electronic-systems units administered from that site; no first-party ARIN remark or .mil source ties AS707 explicitly to a named unit, so this link is not stated as fact [Unknown] — ARIN org record

Related ASNs

none confirmed [Unknown]

Analyst note

Dormant DoD/Air Force ASN with no public routing presence, no PeeringDB profile, and no public website. All routing sources (bgp.he.net, bgp.tools, CAIDA/RIPEstat) agree on zero announcements and zero peers. Allocation date recorded from ARIN RDAP top-level autnum registration event, not the separate 2008-06-05 org-record creation date for handle 7ESG (which is a distinct, later event).
