About this ASN.
AS11 is a legacy single-digit allocation registered under ARIN to Harvard University, historically associated with early Cambridge-area internetworking (the "HARV-MITRE-TIP" folklore). The RADB object lists the President and Fellows of Harvard College, maintained by Harvard University Information Technology (HUIT) Network Services. The key triage point is that the ASN is currently dormant: Hurricane Electric records that AS11 has not been visible in the global routing table since April 15, 2024, and it announces no IPv4 or IPv6 prefixes today. Harvard's live address space is announced operationally via AS1742 (HARVARD-EDU), so AS11 functions as a legacy/secondary institutional handle rather than an active production network. The ARIN ASN RegDate of 1984-07-04 is the registry date; the original assignment predates the modern registry refresh. For analysts, AS11 will appear in registries but should not be expected to carry live routes, and any sudden reappearance in the global table is worth flagging. No notable public abuse signal was found as of June 2026.
