About this ASN.

Updated  ·  Confidence: High

AS119 is a legacy summer-1987 allocation registered under ARIN to the American Mathematical Society (OrgId AMS-26-Z, Providence, RI), carrying the handle "AMS-AS." The ARIN RDAP RegDate is 1987-06-24 (ASN updated 2012-04-02; org entity record from 2009-12-16). The AMS was founded in 1888 as the New York Mathematical Society, reorganized under its present name and became a national society in 1894, and moved its headquarters from New York City to Providence, Rhode Island in 1951; it has roughly 30,000 members. As of June 2026 the ASN is dormant — no originated prefixes in the global routing table, a legacy stub holding (the AMS web presence today does not originate prefixes via AS119); dormancy is inferred from the absence of prefixes and is not contradicted by any source. For triage this is a dormant nonprofit legacy ASN; live origination would be anomalous. No notable public abuse signal was found as of June 2026.
