AS22

AS22 is a legacy U.S. government allocation registered under ARIN to the Navy Network Information Center (NNIC) in Virginia Beach, VA. A common assumption pairs this number with NASA, but that is incorrect: the current ARIN registry shows it held by the U.S. Navy, and historically the IANA legacy list labeled AS22 as "NOSC" (Naval Ocean Systems Center, a San Diego Navy lab later folded into SPAWAR/NAVWAR), while NASA Ames actually held AS23 and AS24. As of June 2026 the ASN originates five IPv4 prefixes (including 128.34.0.0/16, 128.49.0.0/16, and 198.253.16.0/20) and two IPv6 prefixes for roughly 139,520 IPv4 addresses, and its sole upstream is AS668 (the U.S. Department of Defense / DREN), so it is routed exclusively behind DoD networks. For triage, encountering AS22 indicates U.S. military network space — not NASA — and it behaves as a clean, low-profile institutional allocation. One prefix (198.253.16.0/20) is flagged IRR/RPKI-invalid by Hurricane Electric, which is a routing-hygiene note rather than evidence of abuse. No notable public abuse signal was found as of June 2026.
