AS622
Operated by DNIC-ASBLK-00616-00665 - United States Department of Defense (DoD).
Summary
- // analyst note
- Block-member ASN (no individual RDAP object); registry facts inherited from the covering DNIC-ASBLK-00616-00665 record. All routing sources agree on zero announcements/zero peers. A single unrouted-angle claim naming a 'Navy PENS-NET-AS' identity was not corroborated and is excluded.
- // security note
- NEUTRAL/DATED: no public abuse, threat-feed, or NANOG-archive listing specific to AS622 found as of 2026-07-17; currently unrouted so no active attack surface tied to live traffic.
About this ASN.
AS622 is a Department of Defense-administered autonomous system number sitting inside ARIN's DNIC-ASBLK-00616-00665 block, a single contiguous registration spanning AS616 through AS665 held by the United States Department of Defense and administered day-to-day by DISA-Columbus (Defense Information Systems Agency). ARIN's RDAP lookup for autnum 622 resolves with no individual per-ASN object; it returns the block-level record directly, whose top-level registration event dates to 1990-04-19 and whose last-changed event is 2025-09-12 — these are first-party RIR registry facts, not IEEE/OUI-style scrape artifacts, and belong to the covering block that AS622 falls under. Operationally, AS622 is dormant: every routing source checked — RIPEstat, CAIDA AS Rank, and bgp.he.net — agrees it announces zero IPv4 and zero IPv6 prefixes, has zero observed BGP peers, and a customer cone limited to itself (0 prefixes, 0 addresses). CAIDA ranks it 79,459 with seen:false, consistent with an ASN that exists in the registry but carries no live routed traffic. RPKI validation does not apply since there are no announced prefixes to check against a ROA. No public abuse, threat-feed, or NANOG-archive mention specific to AS622 turned up, and registry contact routes to two DISA-Columbus mailboxes for NOC/abuse and registration matters respectively.
- Country / RIR
- US, ARIN [Confirmed] — RIPEstat as-overview (authoritative_rir would be arin; abuse-contact-finder confirms ARIN)
- Allocated
- 1990-04-19 — ARIN RDAP autnum TOP-LEVEL registration event on the covering DNIC-ASBLK-00616-00665 block record (distinct from nested entity/POC registration dates, which range 1993–2009 and are excluded); last changed 2025-09-12 [Confirmed] — https://rdap.arin.net/registry/autnum/622
- Org status
- Active per ARIN RDAP status field [Confirmed] — https://rdap.arin.net/registry/autnum/622
- Website
- no independent operator website verified for AS622 specifically; a third-party listing (ip2location) associates the domain nic.mil, but it did not resolve during this research [Unknown] — https://www.ip2location.com/as622
Abuse contact
disa.columbus.ns.mbx.hostmaster-dod-nic@mail.mil (NOC/technical/abuse); disa.columbus.ns.mbx.arin-registrations@mail.mil (admin/registrations)
Security/abuse context (NEUTRAL, DATED)
no public abuse, threat-feed (Spamhaus, abuse.ch/URLhaus), or NANOG-archive listing specific to AS622 found as of 2026-07-17; currently unrouted so it presents no live-traffic attack surface
Network & routing
- Network type
- government/military ASN block member, not a commercial ISP/content/cloud network; currently unannounced/dormant [Confirmed] — https://bgp.he.net/AS622
- Routing/size
- 0 IPv4 and 0 IPv6 announced prefixes; 0 observed BGP peers (RIS 0/326 v4, 0/322 v6); customer cone = self only (1 ASN, 0 prefixes, 0 addresses) [Confirmed] — https://stat.ripe.net/AS622, https://asrank.caida.org/, https://bgp.he.net/AS622
- CAIDA AS rank
- 79459;
seen: false[Confirmed] — https://asrank.caida.org/ - RPKI posture
- not assessable — no announced prefixes exist to validate against a ROA [Unknown / not applicable]
- Peering policy
- no dedicated public peering-policy page found for AS622 or the wider DoD block; consistent with an ASN that currently announces nothing [Likely] — https://bgp.he.net/AS622
- Geo footprint
- US (CAIDA country ISO); registrant address 3990 E. Broad Street, Columbus, OH 43218; admin/NOC address DISA-Columbus, 300 North James Road, Whitehall, OH 43213 (CAIDA lat/long are 0,0 placeholder defaults, not real coordinates — Unknown) [Confirmed for country/address; Unknown for coordinates] — https://rdap.arin.net/registry/autnum/622
- Registrant/operator
- United States Department of Defense (DoD), administered by DISA-Columbus [Confirmed] — https://rdap.arin.net/registry/autnum/622
- Registry object
- AS622 has no individual ARIN autnum record; RDAP resolves to the block-level object DNIC-ASBLK-00616-00665 (handle AS616, range AS616–AS665) [Confirmed] — https://rdap.arin.net/registry/autnum/622
- Analyst note
- A single-source claim from one research angle described AS622 as a "Navy Network Information Center (PENS-NET-AS)" ASN; this is not corroborated by ARIN RDAP (which shows only the DoD-wide DNIC-ASBLK-00616-00665 block, no Navy-specific or PENS-NET-AS designation) or by any other angle, so it is treated as unverified and excluded from the Fields/JSON above.
