AS11743 — EBSCO
AS11743 announces 3 IPv4 prefixes covering 768 addresses and 0 IPv6 prefixes.
About this network
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.
