AS118

AS118 is a legacy summer-1987 DoD/DNIC allocation registered under ARIN to the United States Department of Defense, carrying the handle "DNIC-AS-00118" and associated with the Navy Network Information Center (NNIC). It was allocated 1987-06-22, and its registry record was last updated 2025-09-12 — so it is still administratively maintained even though it is not routed. Its historical label was "NSWSES-NAVY-AS — Naval Ship Weapons Engineering Systems" (the Naval Ship Weapons Engineering Station, Port Hueneme). As of June 2026 it is dormant — IPinfo classifies the ASN as "Inactive," with 0 IPv4/IPv6 and no prefixes found. For triage this is a dormant Navy DNIC number; the 2025 registry refresh shows it is still administratively tracked but not announcing. No notable public abuse signal was found as of June 2026.
