About this ASN.

Updated  ·  Confidence: High  ·  3 sources  ·  How this page is checked

AS98 is a legacy allocation registered under ARIN to The Rockefeller University (OrgId THEROC-Z), carrying the canonical handle "ROCKEFELLER-AS." The Rockefeller University is a biomedical research institution in New York City, and this is one of the earliest academic ASN allocations on record: the ARIN whois ASNumber RegDate is 1987-02-10. The registration is active and the holder matches the historical association — an unbroken institutional holding. AS98 is actively routing as of 2026-06-19: RIPEstat routing-status confirms 1 IPv4 prefix (129.85.0.0/16) covering 65,536 IPv4 addresses, with full visibility across all 327 RIS full-feed peers and 2 observed BGP neighbours. Last-seen timestamp is 2026-06-19. No IPv6 prefixes are announced. The /16 block 129.85.0.0/16 represents the university's primary address space and has been continuously in routing tables since at least 2001-09-13 (RIPEstat first-seen). For triage this is an established university network where clean academic traffic is expected. No notable public abuse signal was found as of June 2026.
