About this ASN.
AS110 is a legacy spring-1987 allocation registered under ARIN to Xerox Advanced Information Technology (OrgId XAIT, 4 Cambridge Center, Cambridge, MA), carrying the handle "XAIT-AS" — the Cambridge, MA advanced-research arm of Xerox. The ARIN RDAP RegDate is 1987-05-07, but the autnum record is essentially frozen: its last-changed date is 1991-01-10, with no modern update (the org entity was refreshed 2011-09-24). It is dormant — announcing no prefixes, with no peers or upstreams, and CAIDA AS Rank lists it with negligible/zero customer cone. The 1980s/1990s-era contacts and frozen record make this a textbook idle institutional allocation. (Note: AS109 — Cisco — sits between this and AS108 and is already enriched; it is not part of this batch.) For triage this is the lowest-priority kind of entry: a registered-but-idle legacy ASN. No notable public abuse signal was found as of June 2026.
