Autonomous system
AS13315 HBSNET
Unclassified ARIN
Summary
Harvard Business School
education research
The school holds the autonomous system; the university holds every one of its addresses.
What it's used for
- The network of a university business school. 12,544 addresses across three IPv4 prefixes, one observed BGP neighbour, and no IPv6 announced.
Notable
- The AS handle is
HBSNETand the holder is the business school. - All three blocks are registered to the parent university.
- The prefixes are
199.94.0.0/19,199.94.32.0/20and199.94.48.0/24, with netnames199-94-0-0-19,199-94-32-0-20and199-94-48-0-24.
Interesting
- A faculty running its own autonomous system inside a university that holds the address space is an organisational boundary made visible in routing. The school wanted control of its own announcements; the university kept the registration. Both facts are true at once and only the pair of records shows it.
- The netnames restate the prefixes, so every one of them is derived rather than written. Where a European record from the same era carries a company, a date or a city, these carry the address a second time.
- Three graded blocks from one contiguous region are the record of space granted in stages, each new piece taking the next size that fit. They are announced separately because they were received separately, not because they go anywhere different.

Reputation
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: 447 networks and 1,843 prefixes, as published 2026-11-01. 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.
