AS218

AS218 is a legacy autonomous system number registered under ARIN to Air Force Systems Networking (AFSN), a U.S. Air Force / Department of Defense entity headquartered at Maxwell-Gunter Annex Air Force Base in Montgomery, Alabama. The ASN name AFOTECPCNET-AS preserves its origin as the local PC network of the Air Force Operational Test and Evaluation Center (AFOTEC), the USAF's independent operational test agency that evaluates weapon systems before deployment. Allocated on 1988-07-29 per the ARIN RDAP autnum top-level registration event, it is one of the oldest ASNs in the ARIN registry and predates the modern commercial Internet. The key triage point for AS218 is that it is operationally dormant: every routing source consulted (RIPEstat, CAIDA AS Rank, bgp.he.net) agrees it announces zero IPv4 and zero IPv6 prefixes, is seen by zero RIS peers (0/327 v4, 0/324 v6), and shows a CAIDA degree of zero across upstreams, peers, and customers. Its CAIDA AS rank of 79,459 and singleton customer cone reflect complete routing inactivity. The autnum was last changed 2008-08-18, while the registering org (handle 7ESG) carries separate entity-level events; neither displaces the 1988 allocation date. Administrative and abuse handling routes through DISA-Columbus (Defense Information Systems Agency, Columbus, Ohio), which manages ARIN registrations for DoD networks. No notable public abuse signal was found as of June 2026 — not in Spamhaus ASN-DROP, NANOG archives, AbuseIPDB, or any crowdsourced feed — which is meaningful rather than a data gap, since a dormant ASN originates no traffic to attribute.

Operator

Air Force Systems Networking (AFSN), U.S. Air Force / Department of Defense; ASN name AFOTECPCNET-AS originally the AFOTEC PC network at Maxwell AFB, AL [Confirmed] — ARIN RDAP autnum/218

Country / RIR

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

Allocated

1988-07-29 (ARIN registry date from autnum top-level events, NOT an IEEE date — IEEE publishes no ASN registration dates); last changed 2008-08-18 [Confirmed] — ARIN RDAP autnum top-level events

Org status

active U.S. federal government entity — Air Force Systems Networking (org handle 7ESG), Maxwell-Gunter Annex AFB, Montgomery, AL; ARIN registration remains active [Confirmed] — ARIN RDAP autnum/218

Contacts

abuse / admin via DISA-Columbus (handle REGIS10-ARIN), disa.columbus.ns.mbx.arin-registrations@mail.mil, +1-844-347-2457 ext. 2, 300 North James Road, Whitehall, OH 43213; org address 501 East Moore Dr., Bldg 884, Rm 1100, Gunther Annex, Maxwell AFB, AL 36114

[Confirmed] — ARIN RDAP, RIPEstat abuse-contact-finder

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found as of 2026-06-19 — not in Spamhaus ASN-DROP, NANOG archives, or AbuseIPDB; ASN is dormant (0 routes, 0 peers), so the clean profile is meaningful — spamhaus.org/drop/asndrop.json, marc.info NANOG archive, bgp.he.net/AS218

Network & routing

Network type

U.S. government / military internal network; legacy and operationally dormant [Confirmed] — ARIN RDAP, bgp.he.net/AS218

Size

dormant — 0 IPv4 prefixes / 0 IPv4 addresses and 0 IPv6 prefixes; CAIDA customer cone = 1 ASN (itself), 0 prefixes, 0 addresses [Confirmed] — RIPEstat routing-status / CAIDA AS Rank / bgp.he.net (2026-06)

Routing/peering

NOT announced — 0 RIS peers seeing it (0/327 v4, 0/324 v6); CAIDA degree total 0 (customer 0, peer 0, provider 0); no upstreams or peers visible in any source [Confirmed]. No public peering policy found (DoD/military ASN of this vintage publishes none) [Unknown]

RPKI

not assessable — AS218 announces no prefixes, so there are no ROAs to validate [Confirmed] — RIPEstat routing-status

Notable usage

originally provisioned as AFOTECPCNET, the LAN/WAN supporting the Air Force Operational Test and Evaluation Center at Maxwell AFB, AL; AFOTEC is the USAF's independent operational test agency. Currently carries no active BGP routes

Related context

PeeringDB org entry for Air Force Systems Networking (org/20118) lists other AFSN ASNs but not AS218, consistent with AS218 predating or sitting outside their PeeringDB scope [Likely] — peeringdb.com/org/20118

Analyst note

encountered as a dormant legacy military ASN; WHOIS/RDAP resolve to Air Force Systems Networking, but the ASN carries no live routing. Clean, inactive, government-administered ASN. RDAP endpoint timed out on first fetch but returned full data on retry.
