Summary
EBSCO Industries, Inc.
enterprise legacy
EBSCO is EBSCO Industries, Inc., the privately held Birmingham, Alabama conglomerate best known for EBSCO Information Services — the research databases and discovery services that most university and public libraries subscribe to. This is a corporate enterprise network.
What it's used for
EBSCO's own connectivity. RIS sees 3 IPv4 prefixes, 768 addresses, no IPv6, and 3 observed neighbours. Three /24s and three adjacencies is a leaf enterprise: transit in, nothing sold onward. All three prefixes register in ARIN to EBSCO Industries, Inc. under the handles EBSCONET, DYNAMIC and UU-208-247-102. Registrant and originator match, so there is no third-party or leased space in the inventory.
The one sampled PTR, uc.ebsconet.com on 192.73.31.5, is first-party: ebsconet.com is EBSCO's own domain, and uc most plausibly names a unified-communications host. A corporate service on corporate space announced by the corporate AS.
Notable
There is a trap worth naming here and then dismissing. EBSCO's most visible business is publishing library and academic databases, which tempts an education label. That would be wrong. The classification rule is what the space carries and who the operator is, not who its customers are: EBSCO is a for-profit conglomerate with holdings well beyond publishing, and this AS carries its corporate estate, not a campus.
Interesting
The UU-208-247-102 handle is Level 3 / former UUNET-lineage provider-assigned space reassigned to EBSCO — a carrier SWIP, not an outside registrant. Notably, the customer-facing EBSCO research platforms that libraries actually query are not visibly served out of these 768 addresses; the public product almost certainly lives in cloud and CDN space, leaving this AS as the corporate edge.

Interconnection

Internet exchanges
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 2026-10-14, 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 1,773 prefixes, as published 2026-10-13. 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.
