Summary
OCLC (Online Computer Library Center)
enterprise legacy
OCLC-AS is the network of OCLC, the Online Computer Library Center — a nonprofit
library cooperative based in Dublin, Ohio, best known for running the WorldCat
union catalog.
What it's used for
- Delivering OCLC's library technology services to member libraries worldwide: cataloging, resource sharing, and WorldCat lookups.
- Corporate and data-centre networking for OCLC's own operations from its Dublin, Ohio campus.
Notable
- Institutional address space: an IP here belongs to a nonprofit membership organisation serving libraries, not to a residential subscriber or a commercial host renting capacity.
- The allocation is sizeable — tens of thousands of IPv4 addresses — which is a legacy of an early-1995 ARIN registration made when address space was handed out generously to established institutions.
Interesting
- OCLC sits in an unusual middle ground: not a university, not a commercial ISP, but a library-sector cooperative whose services quietly sit behind catalog lookups at thousands of academic and public libraries.
