Summary
Health and Hospital Corporation of Marion County
government enterprise legacy
HEALTH-AND-HOSPITAL-CORPORATION-OF-MARION-COUNTY is HHC, the public municipal corporation for Marion County, Indiana (Indianapolis). It is not a private hospital group: HHC is a statutory public body that runs the Marion County Public Health Department, Eskenazi Health — the county's public hospital, formerly Wishard — Indianapolis EMS and county long-term care.
What it's used for
RIS sees three IPv4 prefixes, 208.88.104.0/24 through 208.88.106.0/24 — 768 addresses — no IPv6, and one observed BGP neighbour. Small, contiguous, single-homed: an institutional edge network, not a provider. One upstream and three /24s cannot serve subscribers and would be absurd for a carrier, which would show hundreds of peers. What this space carries is the organisation's own internet-facing estate: public-facing health and hospital services, plus whatever remote access clinical and county staff use.
Notable
The reverse DNS is the giveaway that this is a two-identity organisation. Sampled addresses split cleanly between .hhcorp.org (the corporation itself) and .wishard.edu (the hospital's long-standing academic-affiliated domain, retained from the Wishard Memorial era). Both wear the same generated per-address template, on space registered in ARIN directly to org HEALTH AND HOSPITAL CORPORATION OF MARION COUNTY. Registrant, announcer and rDNS all agree.
Interesting
The .edu domain is the artefact worth flagging. It reflects the hospital's teaching affiliation with Indiana University's medical school, not an education network — the space is classified by what it carries, which is a county public-health and hospital authority.
