Summary
Woods Hole Oceanographic Institution
research education legacy
WHOI-WOODSHOLE is the network of the Woods Hole Oceanographic Institution, the private non-profit ocean-science research centre on Cape Cod, Massachusetts, and one of the largest independent oceanographic institutions in the United States. RIS sees 9 IPv4 prefixes, roughly 50,400 addresses, no IPv6, and 3 observed BGP neighbours.
What it's used for
Campus and research connectivity: laboratories, scientific computing and data archives, the institution's graduate programme, and its shore-side support for ships and instruments. The core of the inventory is the legacy 128.128.0.0 space — a /17, a /19, a /20 and a /21 — all registered to WHOI itself under WHOINET. Three further blocks out of 199.92.160.0/21 register to Level 3 Parent, LLC: that is provider-assigned space announced by the customer, the ordinary carrier-allocation pattern, not a third-party registrant of the kind that signals leased or brokered addresses. Three neighbours against 50k addresses is a research end-site with a few upstreams, exactly as expected.
Notable
One prefix is registered to WHOI under the netblock handle KNORRNET — 192.147.41.0/24. R/V Knorr was WHOI's long-serving research vessel, best known as the ship from which the wreck of the Titanic was located in 1985. A /24 named for a ship is a good reminder that an oceanographic institution's network extends past the shoreline: shipboard and expedition networks need routable address space too, and the naming outlives the hull.

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-15, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,782 prefixes, as published 2026-10-16. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
