About this ASN.

Updated  ·  Confidence: High

AS106 is a legacy spring-1987 allocation registered under ARIN to General Dynamics Mission Systems, Inc. (OrgId GDAIS-4, Santa Clara, CA), carrying the handle "GDAIS-ASN-106." It is the corporate AS of GD Mission Systems, a major U.S. defense-electronics contractor; the handle and earlier labels ("General Dynamics Advanced Information Systems," with GTE Government Systems lineage further back) were rebranded as the parent consolidated its information-systems units under GD Mission Systems. The ARIN RDAP RegDate is 1987-04-28 (autnum updated 2005-07-18; org updated 2019-05-28). It is actively announcing a small enterprise footprint of 6 IPv4 prefixes (137.100.136.0/22, 137.100.16.0/20, 192.206.187.0/24, 65.121.28.0/24, 137.100.132.0/22, 137.100.144.0/20), with upstream AS3356 (Lumen/Level 3). For triage this is an active corporate/defense-contractor network with a low-abuse profile — a legacy allocation in steady enterprise use. No notable public abuse signal was found as of June 2026.
